Question

Choose the properties that the following element may have based n its location in the periodic table.

Magnesium (Mg):
- dull
- less reactive than sodium
- a gas

Answer 1

Answer: Less reactive than sodium

Why: Due to being in the second period, we can say that Mg has two electrons as opposed to one. More electrons generally means less reactive. Because Mg is a metal, dull might not make sense, and it wouldn’t be a gas.
