Question

Use the periodic table to choose the element that matches each description.

halogen:
group IIA:
nonreactive:
alkali metal:

Answer 1

here's a periodic table: ptable.com

are you given a list of elements? if so, look at the periodic table to see which category each element belongs to. halogens are in group 7 (the second to last column). group IIA elements are the second column. "non-reactive" most likely refers to the noble gases (last column). alkali metals are group I (first column)
