equal
The atomic number and number of protons are always the same in a normal element.
They have the same number of valence electrons (electrons in their outermost shell). They do not have the same number of shells however.
The number of protons and electrons in chlorine is 17
the proton number is 15
For neutral atoms, the electron number is always the same as the proton number.For ions, charged atoms, the proton number is different than the electron number by the charge (e.g. a hydrogen ion, H(+1) has 1 proton and 0 electrons, 1 more proton than electrons).
The atomic number corresponds to the number of protons in the nucleus of an atom. It also corresponds to the number of electrons in a neutral atom. A neutral atom, you'll recall, is one where the number of electrons equals the number of protons in the nucleus of an atom. We remember that atoms often "loan out" or "borrow" electrons, so the electron count will not always equal the proton count.
There is no specific number of electrons that a proton can attract. For example, in a neutral atom; a proton attracts nearly one electron and there is a higher attraction in anions and lesser number in cations.
Atomic number = Number of protons = Number of electrons
the number of proton=the number of electron= 12
there is the same number of electrons ans protons. and the proton number is 6. so you have 6 electrons.
Atomic Number
The proton number of an atom determines what element it is an atom of. That is, it determines the chemical properties of the atom. It does this because the charge on the neutron is neutral, which means that the total charge of the nucleus is equal to the proton number, which it turn means that the number of electrons in the uncharged atom is equal to the proton number. And that in turn determines which electron shells will be filled and what valence electrons available. In this context, the proton number of the nucleus is the atomic number of theelement.
