The number of protons that are found is an atom is referred to as the atomic number. This number is also referred to as the proton number. More »

Each atom contains an equal number of protons and electrons; these particles will be equal in value to an element's atomic number. For example, the element gold, or AU, has an atomic number of 79, meaning it has 79 proto... More »

The element carbon contains six protons in its atomic structure. Carbon has six neutrons that exist with the protons, found in the nucleus of each atom of carbon. More »

The number of protons in the nucleus of an atom determines its atomic number. Each element on the periodic table has a different number of protons in its nucleus and its own atomic number. More »

To find the mass number of an element or isotope, add the neutrons and protons in one atom. Hydrogen is just one element with multiple isotopes occurring naturally, appearing in atomic form with just one proton (mass num... More »

The atomic number of an atom is the number of protons that resides in the nucleus, while the mass number is the number of protons and neutrons combined. The atomic number determines the type of element an atom, while the... More »

To find the number of neutrons in an atom, subtract the number of protons in the atom from the atom's mass. These numbers are found on the periodic table of elements. More »
