The basic building block of matter and everything around us is called what?

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

Answer: (B)

Atoms are the basic unit of matter. They are the smallest units that retain the properties of an element and consist of a central nucleus containing protons and neutrons, with electrons orbiting around it. When atoms bond, they form molecules—the next level of complexity. The nucleus is just the center of the atom, not the entire building block, and cells are the basic units of life rather than matter in general. So the correct answer is atom.
