The number of protons.
The atomic number is the number of protons in an atom.
The number of protons in the atomic nucleus determines what element it is. Each element has a unique number of protons, known as its atomic number.
The atomic number of an element determines the number of protons in its nucleus, which in turn determines its chemical identity. Elements with different atomic numbers have different properties due to their unique number of protons.
The number of protons determines the element's atomic number. When combined with the number of neutrons, it determines the element's atomic mass.
Atomic Number
The atomic number of an element is determined by the number of protons.
Yes. The number of protons is what determines atomic number.
The atomic number is equal to the number of protons in a chemical element.
The number of protons, which are found in the nucleus of an atom.
Atomic number is the number of protons in the nuclei of the atoms of an element. It is the number of protons that determines the atomic number. In a neutral atom, the number of electrons equals the number of protons. So in a way you could say that atomic number determines the number of electrons in a neutral atom.
The number of Protons in the nucleus determines the atom's Atomic number.
