Question

PLEASE HELP WILL MARK BRAINLIEST Marie discovers boxes of elements in a storage room. The boxes do not say which elements they contain, but they do have information about their locations on the periodic table. What kind of information would allow Marie to determine which boxes contain the most reactive elements. PLEASE MAKE THE ANSWER SCHOOL APPROPRIATE

Answer 1

Answer:

The reactivity of metals increases as you move left in a period and as you move down in a group, so Marie needs to know the period and group of the element inside each box. Boxes that show locations in groups 1 or 2 or in period 8 contain the most reactive elements.
