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...

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.

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.


Elements are identified mainly through their atomic numbers, which are the number of protons present in an atom of an element. The periodic table gives each element with its atomic number and atomic weight. The atomic nu...

The identity of an element is determined by the total number of protons present in the nucleus of an atom contained in that particular element. An atom is the smallest fundamental unit of an element.

The atomic number is the value given to the number of protons in the nucleus of an atom. This value is the same as the charge value of an atom.

The number of protons an atom has depends on what element it is. A hydrogen atom, for example, only has one proton. A nitrogen atom has 7 protons, an atom of antimony has 51 protons and an atom of radium has 88 protons.
