An atom is the smallest building block of matter atoms are made of neutrons, protons and electrons the nucleus of an atom is extremely small in comparison to the atom.
The number of protons, neutrons, and electrons in an atom can be determined from a set of simple rules the number of protons in the nucleus of the atom is. Structure of the atom matter has mass and takes up space atoms are basic building blocks of matter, and cannot be chemically subdivided by ordinary means. An atom is the smallest constituent unit of ordinary matter that has the properties of a chemical element every solid, liquid, gas, and plasma is composed of neutral.
