Question

Name the smallest particle from which matter is made up.

Answer 1

Hint: The smallest particle is indivisible and indestructible containing a central nucleus which is almost ten thousand times smaller than the particle itself. Elements as well as compounds are made up of these small particles.

Complete Step by step answer:
- As we know that the smallest particle from which all matter is composed of is the atom itself. The atom is an indestructible and indivisible particle. Elements are also made up of identical atoms but atoms of each element are different from other and easily distinguishable. Two elements make up the compound composed of atoms which may be present in simple whole number ratios like two hydrogen atoms attached with one oxygen atom to make water. Typically the atom has a size around $100pm$.
- Also, we know that every atom consists of a nucleus at its centre and one or more electrons having negative charge is bound to that nucleus. Nucleus possesses neutrons that are without any charge and protons which have a positive charge, so if the number of protons is equal to the number of electrons then an atom is considered as electrically neutral. If the number of electrons is more then, the atom is negatively charged and if the protons are more than, it has a positive charge and such atoms are commonly called ions.

Hence the answer is atom.

Note: The number of protons in the nucleus of an atom is described as the atomic number informing about which chemical element the atom belongs and the total number of neutrons and protons of an atom gives the mass number of the atom.
