Question

electron and proton ke bare main batao
but in paragraph ​

Answer 1

Answer:

Protons and neutrons are in the center (nucleus) of the atom. ... Proton—positive; electron—negative; neutron—no charge. The charge on the proton and electron are exactly the same size but opposite. The same number of protons and electrons exactly cancel one another in a neutral atom.

Answer 2

Answer:-

Electron:

• It is a fundamental particle which has a negative charge.

• It was discovered by J.J. Thomson.

• The charge on an electron is approximately 1.6 * 10⁻¹⁹ coulomb/gm.

• The Molar mass of an electron is 5.48 * 10⁻⁴ g/mol.

• The charge on an electron is measured by the oil drop experiment which was done by Millikan.

Proton:-

• A proton is defined as a sub - atomic particle which has a mass nearly 1 amu & a charge of + 1 unit.

• It was discovered by Goldstein.

• Actual charge of a proton is nearly 1.602 * 10⁻¹⁹ coulomb.

• Mass of a proton is 1.672 * 10⁻²⁷ kg or 1.0072 amu.

• Proton is also known as a nucleon.
