Answer:

a. N3-

b. Ca

c. As

d. Al

Explanation:

a. N or N3-

In this case, the largest species is N3- because it has 3 additional electrons in contrast to the neutral atom.

b. Ca or Ca2+

In this case, the largest species is Ca, because Ca2+ has 2 fewer electrons than the neutral atom of Ca.

c. Si or As

To analyze these elements, is is necessary to look for them in the Periodic Table of elements:

Since the atomic radius increases from top to bottom and from right to left, the largest is As.

d. Al or B

In this case, we also have to look for the elements in the Periodic table, and following the atomic radius increase, the largest is Al.
