What is a proton? Find out the proton definition, along with the mass of a proton and a proton's charge. Also, learn where we can find protons in...

Aluminum has 13 protons, 13 electrons, and 14 neutrons. To determine this, look first at the atomic number for aluminum, which is 13. This gives the...

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.

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...

Fluorine Element What is fluorine? The fluorine element is a chemical species that has a total of nine protons and ten neutrons in its nucleus.

What is Atomic Mass? See atomic mass examples, learn the atomic mass definition, how to find the atomic mass of an atom, and the importance of atomic mass.

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.

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.

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 ...
