Finish coming up with the chemical formula for the following ionic bonding combinations of elements. Remember to complete the two-step process of first drawing out the electron dot diagram for each element involved. Then show how the electron(s) are transferred to result in the charged ion the element becomes. Then write your chemical formula that is electrically neutral. (has an overall zero charge)
1) potassium + fluorine (done in class)
2) magnesium + iodine (done in most classes)
3) sodium + oxygen
4) sodium + chlorine
5) calcium + chlorine
6) aluminum + chlorine
7) aluminum + sulfur
The “Metals, Nonmetals, and Metalloids” reading guide is due tomorrow. Also below is a copy of the “Chemical Bonding” notes that we began to take in class today.

The test on matter will be next Wednesday. Complete the test review to be graded on Monday.
MATTER REVIEW QUESTIONS 2017
The atomic model supplies to build your group’s model are now due by next Wednesday.
- The supplies for the atomic model of the element your group was assigned today are due by next Monday. The drawing of the atomic model (probably finished in class today) and the something unique or a use for your element is due by this Friday.
- “Atomic Dimensions & Organizing the Elements” reading guide is due by Wednesday.
Atomic Model Guidelines

Below is the presentation of notes that was continued in class today. Also below is the handout to finish the “Type of Ion” column for homework. You would need to print out two copies of “First 20 elements” to complete the homework if you lost the copy given in class.
First 20 elements
The “Describing Matter” reading guide was completed in class today. Also, be ready for the element name and symbol test on Monday.
Describing Matter 2017
Continue to KNOW the definitions of atomic number and mass number WELL!! Also, continue to study the 40 elements name and symbol from the Elements page to prepare for the test on Monday.
Below is the presentation on the history of atomic theory that was given in class today.

Complete the “Elements” page for homework. The 40 element names and symbols, only, from that page must be learned. A test on those names and symbols will be next Monday, 1/30/17.
Also, KNOW the definitions of atomic number and mass number WELL by tomorrow!
Below is the presentation given in class as notes. The “Identifying Substances and Counting Atoms” pages are due for homework tomorrow.
Identifying Substances and Counting Atoms
The “Measuring Matter” reading guide was completed in class today. You will need the classroom textbook to answer the questions. Therefore, if you were absent you may check one out from Mr. Walker if you can’t finish it at school in the morning or during Advisory class.
