Consider the model of a sodium atom.
Na

Which feature does the model show accurately?

1. the size of the electrons in different shells

2.the shapes of the orbitals in different shells

3.the distribution of electrons in different shells

4. the orientation of the orbitals in different shells

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.
