Answer 1

**Question 22:** The statement "You can find the number of valence electrons by identifying which period it is in" is **False**. The number of valence electrons is determined by the group (or column) of the element in the periodic table, rather than the period (or row).

**Question 23:** An element in group 17 on the periodic table would have **7** valence electrons. So the correct answer is **b. 7**.
