Question

Which pair of elements has chemical properties which are most similar A) Li and Be B) Li and Mg C) Be and Na D) Be and Mg

Answer 1

D) Beryllium and Magnesium

Step-by-step explanation:

All elements in the periodic table that are "grouped" into vertical columns have similar properties, and are called a "family"

Lithium and Beryllium are both metals but one is alkaline earth metal and the other is just an alkali metal, and they're not in the same group

Lithium and Magnesium are the same thing as said above, they're not in the same group

Same with Beryllium and Sodium

Beryllium and Magnesium are both in the same group so they would have the properties most similar to each other
