An atom of any element consists the electron, proton and neutron.
An atom is the smallest possible particle of any chemical element, which will retain its chemical properties.
An atom consists of 3 subatomic particles - electrons, protons and neutrons. Electrons have a negative charge, protons have a positive charge and neutrons have no charge.
An atom of any element consists the electron, proton and neutron.
Electron: 9.108 × 10-31 Kg, –1.602 × 10-19 Coulomb
Proton 1.672 × 10-27 Kg, +1.602 × 10-19 Coulomb
Neutron 1.675 × 10-27 Kg, 0 Coulomb
Electron: Revolving around the nucleus and determined the volume of atom.
The nucleus is very small compared to the atom, about 10000 times smaller. The diameter of an atom is in the order of 10-10 m, whereas the diameter of the nucleus in the order of 10-15 m.
The atom is a very dynamic entity. The diagram shows a stylised representation; the reality is that there is absolute bedlam at the atomic level.
The neutron has a very slightly higher mass than the proton.
