A1-Period
B2-Period
C3-Period
Correct Answer
D4-Period

Solution

Alkaline earth metals are found in the second group of the periodic table. Group II elements include; Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba) and Radium (Ra).

Similar to alkaline metals, these elements also do not occur freely in nature and they are also very reactive. $$Mg$$ belongs to the third period.
