Explanation:

Question 1

In the periodic table, vertical columns are called groups or families. Periods are horizontal rows, rows are horizontal, and series is not the term for vertical columns. So the correct answer is D.

Horizontal rows on the periodic table are called periods. Families/groups are vertical columns, and column is vertical. So the correct answer is A.

Elements in the same group (vertical column) have the same number of valence electrons, which determines their chemical properties. Protons and neutrons vary (isotopes, different elements), and electron shells are same for periods (horizontal rows). So the correct answer is D.

Answer:

D. Family/Group
