The number of neutrons can vary, which is the basis for isotopes of an element. Neutrons and protons have comparable mass, with their quantities being the basis for the atom's mass number. The electrons are not considered in this calculation because a single electron mass is extremely ...
Protons in an Ion:Protons are nuclear particles. They reside inside the nucleus and the number of protons determines the atomic number of the atom. The atomic number is the characteristics of an element. By removing or adding electrons on an atom, it will change the net charge on it but...
Except for dark matter, all matter found in the universe is made of molecules. Molecules contain atoms and atoms are the smallest units of matter that retain the properties of the chemical element. The three basic subatomic particles are neutrons, protons, and electrons. It is within the atom...

Each element is defined by the number of protons found in each of its atoms. No matter how many electrons or neutrons an atom has, the element is defined by its number of protons. In fact, it's actually possible to have an atom consisting of only a proton (ionized hydrogen). The peri...
