Chem A Final Study Guide

In addition to the questions below, know the difference between the bonds we learned

about as woll as how to write a chemical formula of a bond. Also have your papers from

the previous $2$ days.

List all the parts of an atom, including their role, charge, and location.

An atom has $11$ protons, $13$ electrons, and $10$ neutrons, what charge does it

have

An atom has $16$ protons, $14$ electrons, and $16$ neutrons, what mass does it have?

Draw the lewis structure and Bohr model for oxygen. Make sure you know which

is which:

Why are valence electrons important?

What are the different types of bonds we learned and characteristics about

them?

What is the most reactive group on the periodic table

What is the least reactive group since it has a full valence shell?

Describe the octet rule and its importance in chemistry:

What is chemistry?

What are the different types of ions?

If an atom has $9$ protons, $10$ neutrons, and $8$ electrons, what is its approximate

molar mass?
