What is the basic building block of matter and everything around us?

• A. Atom
• B. Molecule
• C. Cell
• D. Nucleus

Answer: (A)

Atoms are the basic building blocks of matter. They’re the smallest units of elements that retain the properties of that element. An atom has a nucleus of protons and neutrons, with electrons orbiting around it. When atoms bond, they form molecules—the substances we encounter in everyday materials, including hazardous ones. Cells are the units of life, not all matter, and the nucleus is simply the center part of an atom. So the fundamental building block of matter and everything around us is the atom.
