    An atom consists of a nucleus of protons and generally neutrons, surrounded by an electromagnetically bound swarm of electrons. The chemical elements are distinguished from each other by the number of protons that are in their atoms. For example, any atom that contains 11 protons is sodium, and any atom that contains 29 protons is ...

  8. An atom is an extremely small piece of matter. All normal matter – everything that has mass – is made of atoms. This includes solids, liquids, and gases. The atom cannot be broken to parts by chemistry, so people once thought it was the smallest piece of matter that could exist.

  9. Jan 24, 2024 · Since an atom contains equal number of protons and electrons, it has no overall charge: the positive charges on all the protons are exactly balanced by the negative charges on all the electrons. But sometimes an atom can gain or lose an electron to become what's called an ion.
