Establish the trends for atomic radius, electron affinity and first ionization energy to figure out the correct words for the blank statements

Recall that Atomic radius represents the distance from the nucleus to the outer shell of an element. 

Trend of atomic radius in the periodic table:

decreases going from left to right of a period

increases going down a group
