Based on their locations on the periodic table which best compares the properties of the metalliods arsenic (as) and antimony (sb )

In order to compare the two elements, one must take note of

its placement in the periodic table. As you go down a group in the periodic

table, the metallic property increases. Thus in the problem, Antimony has a

more metallic behavior than Arsenic so that already crosses out statement A and

B from the choices since it is untrue. The number of electron shells meanwhile

decreases as you go down the group. Therefore the answer would be Arsenic has a

more nonmetallic behavior than antimony because arsenic’s atoms have fewer

electron shells.  

HOPE THIS HELPS

Metallic Characteristics: solid at room temperature, lustrous

In Between Characteristics: amphoteric, semiconducting

Nonmetallic: brittle

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.
