What element in the second period has the largest atomic radius answer. com?

There are actually several patterns which we can find in the periodic table of elements. From top going down, the atomic radius increases. Then from left to right it decreases. Therefore the largest element is located on the bottom leftmost of the table. Looking at the second period, the leftmost element is Lithium therefore it is the answer.

Lithium

consider the reaction below.
