an electron has a mass that is much less than a proton.
the innermost atomic shell can hold a maximum of 18 electrons.

Explanation:

1. Elements are made of atoms.
2. Arranged by atomic number.
3. Atomic number = proton number.
4. Nucleus has protons and neutrons.
5. Electrons outside nucleus are negative.
