The atomic number is equivalent to the number of protons or electrons (in the neutral state of an atom).
Number of protons in the nucleus is the atomic number.
The number of positively charged particles in atoms of a given element is equal to the number of protons in the nucleus of the atom. This number is referred to as the atomic number of the element and it determines the element's identity on the periodic table.
Protons are positively charged particles found in the nucleus of an atom. The number of protons in the nucleus determines the element's atomic number. Neutrons are neutral particles also found in the nucleus, and together with protons, they determine the atomic mass of the element.
Protons are positively charged subatomic particles found in the nucleus of an atom. They determine the element's identity by the number of protons present, known as the atomic number. The number of protons also influences the chemical properties of the element.
Protons are subatomic particles that determine the atomic number of an element. The number of protons in an atom's nucleus is what defines its atomic number; this uniquely identifies each element on the periodic table.

False; the atomic number is the total number if protons in the nucleus only.
Protons are positively charged particles found in the nucleus of an atom. The number of protons in the nucleus determines the element's atomic number. Neutrons are neutral particles also found in the nucleus, and together with protons, they determine the atomic mass of the element.

Protons are the subatomic particles represented by the atomic number of an element. The atomic number is equal to the number of protons in the nucleus of an atom, which determines the element's identity on the periodic table.
Protons are subatomic particles that determine the atomic number of an element. The number of protons in an atom's nucleus is what defines its atomic number; this uniquely identifies each element on the periodic table.
The atomic number is the number of protons in the nucleus. The protons are positive particles, and so the number of them is matched by the number of electrons orbiting the nucleus. The organisation of the electrons determines how an element behaves when it reacts.
The atomic number of an element is determined by the number of protons.
An element's atomic number is the # of protons in its nucleus.
The "Atomic number" of an element corresponds to the number of only the protons in the nucleus of its atoms. Add to that the number of neutrons that are also in there, and you have the "Atomic weight".
The atomic number is an indication of the number of PROTONS in the nucleus of the atom of an element.
