It indicates the atomic number of that element.
It indicates the atomic number
An element can be identified by the number of protons in the nucleus of its atoms.
the number of protons
The atomic number of an element represents the number of protons in the nucleus of an atom. Since atoms are electrically neutral, the number of protons in the nucleus must be equal to the number of electrons outside the nucleus, making the atom overall neutral.
The number of protons in a nucleus is called the proton number, or atomic number. It is what defines which element we have.
Do you mean number of protons in a nucleus? The nucleus is part of an atom.
The number of protons in the nucleus of its atoms.
atomic number
Because the atomic number indicates the number of protons per nucleus while the mass number is the sum of the number of protons and the number of neutrons per nucleus, and all atoms except hydrogen-1 have neutrons in their nuclei.
The mass number is the sum of protons + neutrons.
An atom of Carbon has 6 protons in its nucleus.
