Answer 2

HERE IS YOUR ANSWER .....

The smallest unit in the composition of matter is the atom. The atom is composed of a nucleus at the center and one or more electrons orbiting around the nucleus. The nucleus consists of protons and neutrons, collectively called nucleons. The protons are positively charged particles with a mass of 1.00728 amu and the neutrons are electrically neutral particles with mass of 1.00867 amu.

The electrons are negatively charged particles with a mass of 0.000549 amu. The protons and neutrons are about 1836 times heavier than the electrons. The number of electrons is equal to the number of protons thus resulting in a neutral atom of an element. The electronic arrangements determine the chemical properties of an element whereas the nuclear structure dictates the stability and radioactive transformation of the atom.
