The identity of an element is determined by its atomic number. This is the number of protons it has, as well as the number of electrons it has when it's neutral. This number is unique to each element: no two elements have the same atomic number.
The atomic number, which is equal to the number of protons in the nucleus of any atom of the element.
Atomic number is considered as key identity for periodic table.
This is the atomic number (A).

The number of protons determines the element's atomic number. When combined with the number of neutrons, it determines the element's atomic mass.
The number of protons in each nucleus of an atom of the element.
Number of protons or the atomic number of an atom determines what is the element.
The number of protons, which are found in the nucleus of an atom.
The number of protons determines the element, and is the same as its atomic number.
The number of protons determines the element's atomic number. When combined with the number of neutrons, it determines the element's atomic mass.
No that is not true. The number of PROTONS determines what the element is.
Mass Number
The number of protons.
The number of protons in each nucleus of an atom of the element.
The number of protons in each nucleus of an atom of the element.
Its atomic number. In other words the number of positive protons in the nucleus of each atom and the number of negative electrons surrounding the nucleus of each atom.
Number of protons or the atomic number of an atom determines what is the element.
The number of protons.
The number of protons in the nucleus of an atom determines its identity as a particular element. The number of protons is the element's atomic number, and is unique to each element. For example, the atomic number of oxygen is 8, while the atomic number of carbon is 6.
The number of protons in the nucleus of an atom determines the atomic number of the element to which the atom belongs.
The number of protons, which are found in the nucleus of an atom.
