While the number of protons must stay the same to qualify as a particular element, there is no restriction on the number of neutrons that can be found in a nucleus. The different isotopes are identified by their mass number, the total of their protons and neutrons. Answer and Explanation: ...

A neutron is one of the subatomic particles that make up matter. The neutron has no electric charge and a rest mass equal to 1.67493E−27 kg — marginally greater than that of the proton but nearly 1839 times greater than that of the electron.

The standard unit of mass is a kilogram (one kilogram is equal to approximately 2.2. lbs), which might be familiar to you as a unit of weight. Mass and weight are distinct because weight is a measure of the size of the pull of gravity on the object. So the mass of a rubber ball...
Mass Number: The mass number of an atom is the total number of protons and neutrons contained within the nucleus of the atom. The number of protons determines the element and will always equal the atomic number of that element. The number of neutrons can change and will determine which i...
