Which of the following statements is not accurate in regard to the first four energy levels? a. the third energy level can hold a maximum of 18 electrons. b. the fourth energy level is the only energy level to hold an f sublevel. c. an orbital can hold a maximum of two electrons. d. the first energy level has 1 p orbital

D) False

Explanation:

A) True

The third energy level with principal quantum number n =3 will have s,p,d orbitals where the s, p ,d  orbitals can accommodate a maximum of 2,6 and 8 electrons respectively. Therefore, total electron count = 18

B) True

The fourth energy level corresponds to n = 4 with s,p,d and f orbitals

C) True

A given orbital can accommodate a maximum of 2 electrons, one in the spin up and the other in a spin down orientation

D) False

The first energy level has n =1 with only s orbital

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.
