SSC MTS EXAM

Detailed explanation-1: -An atom is the smallest particle of an element, having the same chemical properties as the bulk element. The first accurate theory explaining the nature of matter was Dalton’s Atomic Theory : 1. All matter is composed of atoms, and atoms are indivisible and indestructible.

Detailed explanation-2: -The tiny particles called atoms are the basic building blocks of all matter. Atoms can be combined with other atoms to form molecules. However, they cannot be divided into smaller parts by ordinary means. Each individual atom is made up of smaller particles called electrons, protons and neutrons.

Detailed explanation-3: -Atoms are the smallest building blocks of matter and make up everything around us. Every atom has a center called a nucleus, which is made of particles called protons and neutrons. Electrons move in electron shells around the nucleus. Atoms can bond to one another to form solids, liquids, or gases.
