- Read the newsela article (link to PDF posted to iLearn).
- Review the additional resources (Polar Bears and Penguins, use the interactive periodic table link to see where the metals and nonmetals are on the periodic table)
- Take notes on the different types of bonding and connect this back to what you learned about electronegativity.
- Draw a double bubble diagram in your notes to compare the two types of bonding.
- To turn in: Complete the sentence stems: [You may use these key words metal, nonmetal, covalent, ionic or use other science words]
- In an ionic bond, you would expect to see both ____ and _____ types of elements.
- In a covalent bond, you would only expect to see _______ elements.
- Based on their electronegativities, you would expect ____ elements to pull on electrons more strongly than ______ elements.
- If ______ elements pull more strongly on bonding electrons than _____ elements, then you would expect ______ to be negative and ______ to be positive ions.
- Sodium and chlorine form a compound called salt which is held together by _____ bonds.
- Carbon and hydrogen and oxygen form many different compounds when bonded together in different ways, but almost all of these would be called _____ bonds.
Khan Academy for Honors Classes (optional for others)
New assignments posted on Khan Academy are for Honors classes (Hours 1 and 4). These are only required for my honors students (hours 1 and 4). This first set will be due Sunday, May 17 in addition to the regular work for next week.
If you are not in honors, but are looking to make up points or prepare for physics for next year, you may choose to do the Khan Academy work. This is not required for hours 2, 3, and 5.
Meetings will continue as scheduled
I will continue to follow the schedule for meetings and we will use the Big Blue Button system on iLearn. Please make sure you are checking the iLearn regularly for any other information and to be comfortable finding important links.
Work for the week of May the 4th
Please read this article (it is a section of an online textbook): https://chem.libretexts.org/Bookshelves/Physical_and_Theoretical_Chemistry_Textbook_Maps/Supplemental_Modules_(Physical_and_Theoretical_Chemistry)/Physical_Properties_of_Matter/Atomic_and_Molecular_Properties/Electronegativity
Before finishing the sentence stems, sketch the periodic table in your notes and make a visual representation of the trend for electronegativity on the periodic table.
For the sentence stems, feel free to choose from these words to help you: increase, decrease, strong, weak, left, right, up, down, top, bottom, larger, smaller. You may use other words, and not all of these words are needed, but I want to make sure you keep your sentences simple. Please turn in complete sentences on iLearn.
SENTENCE STEMS:
As you read from top to bottom on the periodic table, the number of protons in the nucleus of the atoms __.
As you read from left to right on the periodic table, the number of protons in the nucleus of the atoms __.
As you read from top to bottom on the periodic table, the number of electrons in a neutral atom of the elements __.
As you read from left to right on the periodic table, the number of electrons in a neutral atom of the elements __.
As you read from top to bottom on the periodic table, the electronegativity of the elements __.
As you read from left to right on the periodic table, the electronegativity of the elements __.
As you read from ____ to ___ on the periodic table, the electronegativity increases, but the atomic radius decreases
Elements with a small atom radius tend to have __ electronegativity.
Elements with a __ atomic radius tend to have weak electronegativity.
Please let me know if you have any questions. May the fourth be with you.
Meetings continue on iLearn (using Big Blue Button)
We are still meeting this week, so please make sure you are enrolled in iLearn and find the appropriate meeting links.
The platform we will be using is Big Blue Button. Sometimes the audio cuts in and out, so I will try to keep the important comments typed into the public chat. I can also download the public chat, so if you participate in the chat, I can give you full credit.
I know that constantly changing platforms is confusing and frustrating, but this is not anything you cannot handle. I am also sorry that the actions of your classmates are making this harder for everyone.
Tuesday Update April 28
- All meetings will be using Big Blue Button on iLearn, so make sure you are enrolled in iLearn and know where to find the link (it is not hard to find).
- For the work this week, please type into the text box (or copy/paste) so I can properly read your sentences.
- For my own organization, I am not allowing re-takes or re-submissions, but I do expect you to take my feedback and correct your personal notes.
- We will be using the work we do now for later work, so keeping your notes up to date will save you a lot of time later.
- Please read the instructions carefully. I know they are long, but you have all week to read and do the work. Please I would recommend taking notes even when you are reading directions to help you keep track of things and to work through any confusions.
Work for the week of April 27
Please make sure you are checking in with our Google Classroom and iLearn regularly. I post announcements on Google Classroom related to our work and iLearn will have new links and resources added throughout the week. Also, the new information related to our video meetings will be posted to iLearn (we need to use Big Blue Button instead of Google Meet).
This week, I have tried to organize the instructions to be more clear.
What to read: Read this simple wikipedia description of atomic radius.
Questions to answer in your notes: How does this short article relate to the reading from last week? What other questions do you have about what you are learning from these articles?
Visualization or drawings to put in your notes: Make a sketch or drawing to describe the pattern or trend of how atomic radius changes related to where the element is on the periodic table. (To help, check out examples of professionals doing these types of visualizations: Compound Chem, ThoughtCo, Online Textbook. Please do not copy, the point of this exercise is to do the work yourself. Email me if you have questions or issues).
To turn in on iLearn: Fill in the blanks for these sentence stems with words and phrases that makes sense grammatically and scientifically based on the readings.
- As you read from top to bottom on the periodic table, the number of electrons in a neutral atom of the elements ______________.
- As you read from left to right on the periodic table, the number of electrons in a neutral atom of the elements ____________.
- As you read from top to bottom on the periodic table, the atomic radius of the elements ______________.
- As you read from left to right on the periodic table, the atomic radius of the elements ____________.
- As you read from top to bottom on the periodic table, the number of protons in the nucleus of the atoms ______________.
- As you read from left to right on the periodic table, the number of protons in the nucleus of the atoms ____________.
- As you read from ________ to _______ on the periodic table, the number of protons and electrons increase, but the atomic radius decreases
- As you read from ______ to _______ the number of protons, the number of electrons, and the atomic radius all increase
This week’s disruptions to remote learning
The note in Arabic: https://docs.google.com/document/d/1suKCDlHiHF-VurgbE5kP7fCTx4N2LQEq-VKmquXwZF8/edit?usp=sharing
I will be switching all of my meetings to Big Blue Button on iLearn, so look out for more information next week (and keep an eye out for links on iLearn).
Tuesday update
Today is the first day of meetings by hour. I will be following the approved schedule and you can join using the link in Google Classroom (there is also a way to call in if you need that). I have copied the schedule to the bottom of this post.
For this week’s work, the note taking is for your own notes, you do not need to share them with me. The only work that is “collected” are the pre and post reading work (the pre-reading survey, and the quiz).

Changes for the week of April 20
Ms. Alcodray has made a video with some information about the changes.
Here is a detailed document describing the changes. [EDIT: I will update with the correct document when I can, sorry for the confusion.] [EDIT: HERE IS THE CORRECT DOCUMENT]
This week, to simplify things with all of the changes, all of the links to the work and reading are posted to iLearn in the section called “Article of the week.”
All of the work for this week must be done by Sunday at midnight, but I have broken it into 5 steps so you can do a little bit each day.
- Take the pre-reading survey in the “Article of the week” section on iLearn.
- Read the article posted in the “Article of the week” section on iLearn.
- Take notes on things that you already knew in the article AND things that are new to you.
- Take the quiz posted in the “Article of the week” section on iLearn.
- Take any feedback from the week or from the quiz to update your notes.
