Learn the three isotopes of hydrogen. Learn the number of protons and neutrons in each of the isotopes of Hydrogen along with their atomic and mass numbers.

Protons - positively charged particles found in the nucleus of the atom. The number of protons in the nucleus is directly related to the identity of the atom/element and is known as the atomic number.

An oxygen ion has 8 protons and 10 electrons. The number of protons tells us the identity of the element because the number of protons is the same as...

Cations have more protons than electrons, which causes the overall positive charge on the atom. If an atom gains an electron, the ion is called an anion due to the overall negative charge on the atom.
