How many of each subatomic particle type does each of the following atoms contain: a. 90_ag b. barium-132

Silver has 47 electrons, 47 protons and 43 neutrons. Barium has 56 electrons, 56 protons and 76 neutrons.

Explanation:

Atomic number is defined as the number of protons or electrons that are present in a neutral atom.

Atomic number = number of protons = number of electrons

Mass number is defined as the sum of number of protons and neutrons that are present in an atom.

Mass number = Number of protons + Number of neutrons

Atomic number = 47

Mass number = 90

Atomic number = Number of protons = Number of electrons = 47

Number of neutrons = Mass number - Atomic number = 90 - 47 = 43

Hence, silver has 47 electrons, 47 protons and 43 neutrons.

Atomic number = 56

Mass number = 132

Atomic number = Number of protons = Number of electrons = 56

Number of neutrons = Mass number - Atomic number = 132 - 56 = 76

Hence, barium has 56 electrons, 56 protons and 76 neutrons.

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.

have a great day because if you dont you and i will be sad
