Find the Protons, Electrons and Neutrons for nitrogen-3 ion with 7 neutrons

This question appears to be asking about the nitride ion N^ −3 . All nitrogen atoms, by definition, have 7 protons. The number of neutrons varies depending on the isotope. Most will have 7 neutrons, but stable nitrogen atoms with 8 neutrons also exist. Since our ion has a charge of -3, it must have 3 more electrons than it has protons, so there are 10 electrons in all.

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.
