54 protons and 54 electrons
The atomic number of an element is how many protons and electrons (you must have the same amount of protons as electrons) an element has in it's nucleus. The Atomic number= number of protons= number of electrons.
The atomic number is how many protons and electrons the element has. Hope this helps!!!
atomic number
the number of protons in an element is called the atomic number and there is no way to see how many electrons an element has.
The atomic number = Number of protons = Number of electrons
The atomic number of a chemical element is equal to the number of electrons or protons. The number of neutrons = Atomic weight of an isotope (rounded) - atomic number of the element (or the number of protons)
An element's atomic number is equal to the amount of protons in that element. Each atom has a different number of protons and electrons present in their make-up.
It will have 12 electrons.

put it in your mind! The Atomic number. is number of protons, While The Mass number. is number of protons and electrons. when you subtract both get the number of electrons and this for any element but not all elements have same atomic numbers or mass and Rutherford First discover "transmutation" from element to other element which determine by their atomic and mass numbers.
The atomic number of an element _is_ the number of electrons in one of its atoms. Indeed, a sample of an element can be defined as any combination of atoms with the same atomic number. Oxygen is the element with atomic number 8. It is the element whose atoms have 8 electrons in their neutral state (and 8 protons).
You can determine the number of electrons in an element by looking at its atomic number on the periodic table. The atomic number represents the number of protons in the nucleus of an atom, and since atoms are neutral, this also corresponds to the number of electrons.
