Write the nuclear symbol and hyphen notation for each of the following isotopes: a. mass number of 28 and atomic number of 14 b. 26 protons and 30 neutrons

Explanation:

Isotopes are types of atoms of same element with same number of protons and electrons but differ in number of neutrons in their nucleus.

Hyphen notation is written as: Elemental Symbol - (Mass number)

Nuclear Symbol :

a. Mass number of 28 and atomic number of 14.

The element with atomic number 14 is Silicon.

The hyphen notation for this given isotope of a silicon  : Si-28.

Nuclear Symbol  :

b. 26 protons and 30 neutrons.

Mass number of element = 26 + 30 = 56

Atomic number of element = number of proton = 26

The element with 26 atomic number is iron.

The hyphen notation for this given isotope of a iron : Fe-56.

Nuclear Symbol  :

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.
