Answer 1

Here are the answers to your questions based on the arrangement of elements in the Periodic Table:

**Question 8**
Video Question #1: How are the elements arranged on the Periodic Table to show patterns of energy levels or orbitals, valence electrons, families, and oxidation states?

**Answer:**
b - periods and groups

**Question 9**
Video Question #2: Are the lighter elements, or elements with low mass numbers, found at the top or the bottom of the periodic table?

**Answer:**
a - top

**Question 10**
Video Question #3: What do elements in the groups 1A through 8A have in common? (Choose all that apply)

**Answers:**
d - they all have similar properties
e - they all have the same number of valence electrons

(Note: Option b could apply to specific groups, but it is not universally true for all elements in groups 1A through 8A. Options a and c are not correct for all elements in those groups.)
