Answer:

Answer 1: D Answer 2: C

Explanation:

Vertical columns on the periodic table are called families or groups. The elements in each family have similar properties.

For example, the first family (column 1) of the periodic table is known as the alkali metals, and the elements in that family are silver-colored, soft, and highly reactive. The last family (column 18) of the periodic table is the noble gases, and the elements in that family are odorless and colorless gases that are not very reactive.
