Which option describes a common property of the elements, nitrogen (n), phosphorus (p), arsenic (as)? hint: review your periodic table. they have the same amount of reactivity. they have the same amount of atomic mass. they have the same number of valence electrons. they have the same atomic radius size.

The common property of N, P, and As is that they have the same number of valence electrons.

Atoms of nitrogen have the least atomic mass and are smaller and more reactive than those of phosphorus and arsenic.

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
