Solution

Properties of Electrons

1: Electrons are negatively charged particles.

2: The mass of the electron is 1/2000 times lesser than the mass of the proton and neutron. Therefore, the electrons do not contribute to the mass of the atom.

3: An electron has an electric charge of -1.602 × 10-19 Coulombs which is equal and opposite to the charge of a proton.

4: Electrons are subatomic particles found outside the nucleus, unlike protons and neutrons, which are present inside the nucleus.

5: According to the Bohr atom model, electrons are continuously moving around the nucleus in orbits or shells.

6: The invariant mass of an electron is approximately 9.109×10−31 kilograms.

7: Electrons display both particle properties and wave properties.

8: According to the principle of quantum mechanics, the position and momentum of the electrons cannot be determined simultaneously.
