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.

Learn how to count protons and electrons in ions, and see examples that walk through sample problems step-by-step for you to improve your chemistry knowledge and skills.

A molecule with more protons than electrons will also have a positive charge. Do protons have a charge of negative 1? Protons are positively charged subatomic particles.

In a neutral atom, the number of protons and electrons are equal. In a positively charged ion, also called a cation, the number of protons is greater than the number of electrons.

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.

Their number of protons make them a unique type of element. For example, oxygen atoms have 8 protons, hydrogen atoms only have 1, and gold atoms have 79. This number is like the identity of an ...
