Protons have a +1 charge. Electrons have a -1 charge
Look at a Periodic Table.
Li has 3 protons, it is the only element with 3 protons in its nucleus. It also has 3 electrons in the shells outside the nucleus. If another atom has a stronger attraction for that 1 electron, than Li does, it will pull the electron off the Li atom. Now Li has 3 protons, +3, and 2 electrons, -2. Which adds up to +1 . It is a +1 ion. Li+1
Li+ , a lithium ion, has 3 protons and 2 electrons.
Cl-
Li+1.

- The atomic symbol is only an abridged form of the name of a chemical element. - The chemical symbol of neon is Ne; the atomic number is 10. - The atomic number is equal to the number of protons and electrons. - Number of neutrons = Atomic mass of an isotope - Atomic number
Magnesium, with a +2 charge.

Protons: 10 Electrons:10 and Neutrons: 10.
It contains 10 protons and 10 electrons (no. of protons =no. of electrons in ground state) Number of neutrons=Mass number of element- number of protons =19-10 =9
In an atom, 10 protons and 10 electrons. (# of protons = atomic number) =)
The chemical element with 20 protons and 20 neutrons is Calcium(Ca). The number of protons is equal to the number of electrons, and the number of electrons is equal to the atomic number.
