Atoms are electrically neutral because they have the same number of protons and electrons.
All atoms of a given element must have the same number of protons, neutrons, and electrons.
Most of the volume of an atom contains only electrons.
The nucleus is positively charged.
Almost all of the mass of an atom is in the nucleus.
