Detailed explanation-1: -Electrons have an electric charge of −1 and their mass is approximately about 1/2000 the mass of a neutron or proton. Electron charge is usually denoted by the symbol e. It is a fundamental physical constant that is used to express the naturally occurring unit of electric charge which is = 1.602 × 10-19 coulomb.

Detailed explanation-2: -Electrons have electric charge of-1 and the number of electrons in an atom is equal to the number of protons. Hydrogen is the simplest atom with one proton and one electron.

Detailed explanation-3: -electron, lightest stable subatomic particle known. It carries a negative charge of 1.602176634 × 10−19 coulomb, which is considered the basic unit of electric charge.

Detailed explanation-4: -Therefore, the number of electrons in one coulomb of charge is 6 × 10 18 electrons .

Detailed explanation-5: -Protons have a positive electrical charge of one (+1) and a mass of 1 atomic mass unit (amu), which is about 1.67×10−27 kilograms.
