The atomic number equals the number of protons in an atom, as well as the number of electrons in a stable, electrically neutral atom, it represents the identity of an element ,the simplest form of matter.
In any atom, the number of protons will equal the number of electrons, but only in a neutral atom. Remember that most atoms loan, borrow or share electrons, so the number of protons will not be equal to the number of electrons in all cases. In review, only in a neutral atom will the number of protons equal the number of electrons.
Atomic weight in atomic mass units = the number of protons + the number of neutrons. The number of protons is your atomic number. Subtract that from the atomic weight for the number of neutrons.
The mass number is the total number of protons and neutrons in an atom's nucleus, while the atomic number is the number of protons in the nucleus. The mass number determines the atom's mass, while the atomic number determines the element's identity on the periodic table.
The atomic number of an element is equal to the number of protons in the nucleus of that element; it will identify the element. The number of neutrons of a given element may be different as the element may have a number of isotopes.
The atomic number tells us the number of protons in the nucleus of an atom. It determines the element's identity and its place on the periodic table. Elements with different atomic numbers have different chemical properties.

Atomic numbers represent the number of protons in an atom's nucleus. It also defines the element, as each element has a unique atomic number.
The numbers on Mendeleev's periodic table represent the atomic number of each element, which is the number of protons in the nucleus of an atom. This number determines the element's identity and its placement in the periodic table.
The number of protons and electrons of the atom in a neutral state.
The atomic number.
Atomic number of an atom shows the number of protons in the nucleus of the atom. OR Atomic number of an atom is the number of electrons in the atom when the atom neutrally charged
No element has this atomic number. All atomic numbers are whole numbers.
The number of Protons in an atom, so Hydrogen with 1 proton has the atomic number 1.
The atomic number of an element represents the number of protons in the nucleus of an atom of that element. It determines the identity of the element on the periodic table and distinguishes it from other elements.
Atomic number= number of protons. Hydrogen atomic number=1
The atomic number of an element represents the number of protons in the nucleus of an atom of that element. It is a unique identifying characteristic of an element because different elements have a unique number of protons in their nuclei.
The atomic number represents the number of protons in an atom's nucleus. It determines an element's unique identity and its position on the periodic table. Elements with the same atomic number are the same element, regardless of their isotopic variations.
