you would expect magnesium to be most similar in properties to
a) silicon.
b) potassium.
c) calcium.
d) sulfur.

Explanation:

Elements in the same group (vertical column) of the periodic table have similar chemical properties because they have the same number of valence electrons. Magnesium (Mg) is in Group 2 (alkaline earth metals). Calcium (Ca) is also in Group 2. Silicon (Si) is in Group 14, potassium (K) is in Group 1, and sulfur (S) is in Group 16. So magnesium and calcium share similar properties due to being in the same group.

Answer:

C) calcium.
