What element behaves MOST like magnesium (Mg)? A) S B) Si C) Sn D) Sr

Answer: Option (D) is the correct answer.

Explanation:

It is known that elements which belong to same group will have same properties.

Both Silicon (Si) and tin (Sn) belong to same group and therefore, they have same chemical properties.

Whereas Magnesium (Mg) and Strontium (Sr) also belong to same group, thus, they have same properties.

Hence, we can conclude that Sr element behaves MOST like magnesium (Mg).
