Detailed explanation-2: -Atoms are the building blocks of matter.

Detailed explanation-3: -There are 3 basic particles that make up an atom: protons, neutrons, and electrons. The center of the atom, or the nucleus, contains both protons and the neutrons. Surrounding the nucleus is the electron cloud, where the electrons are existing in the outermost regions of the atom in electron shells.

Detailed explanation-4: -Atoms and molecules are the building blocks of matter.

Detailed explanation-5: -Life exists in a myriad of wondrous forms, but if you break any organism down to its most basic parts, it’s all the same stuff: carbon atoms connected to hydrogen, oxygen, nitrogen and other elements. But how these fundamental substances are created in space has been a longstanding mystery.
