The nucleus consists of protons and neutrons.
Electrons are never found in the nucleus of an atom, along with the protons. They exist in shells that surround the nucleus.
The majority of an atom's mass comes from its nucleus, where the protons and neutrons are joined. The electrons of an atom are so distant and so minuscule in size, that their weight is negligible. When calculating the mass of an atom is therefore protons+neutrons.
Protons and neutrons exist in the nucleus of an atom. The electrons in an atom exist outside the nucleus. All elements have at least one proton; in fact the number of protons, which are positively charged, determines which element it is. Normally, all the elements except hydrogen (H) also contain neutrons, which have no charge (they're neutral, hence their name.)
The isotope carbon-40 doesn't exist !
No it can't. There has to an equal amount of electrons as protons! This atom can't exist.
That would depend on how many protons exist in the nucleus of the atom. An atom with 6 protons is a carbon atom; 7 protons is nitrogen, and 8 = oxygen.

Nucleus
No, only protons and neutrons exist in the nucleus of an atom. Electrons are what produce a negative charge.

It does not exist If it did exist it would be 30Al+
That is called the nucleus. It is positively charged and it makes up most of the atom's mass.

actually protons exist inside the nucleus not outside. Electrons are the ones that exist outside and they don't orbit they are more like clouds around the nucleus,and nothing orbits the atom's nucleus.
When the number of protons is different another atom exist; the number of protons is specific for only one element.
