The atom is neutral
The number of protons in a nucleus depends on which element it is. ( The number of protons is the decider as to which element it is. ) The number of electrons in an atom is the same as the number of protons in the nucleus, but none of the electrons are in the nucleus. Rather, they orbit around the nucleus like planets round a star.
it tells you the amount of electrons the atom has orbitting the atom and the nucleus
One atom. It contains 29 protons in its nucleus with 29 electrons orbitting. Hence copper (Cu) having the atomic number 29.
The number of protons is usually the same as the number of electrons!:)
They have the same number of protons in the nucleus and same number of electrons surrounding the nucleus.
The nucleus of an atom contains only protons and neutrons; there are never any electrons in the nucleus. The number of neutrons is generally equal to or greater than the number of protons.

electrons
Its electrons and protons are the same. just determine its electrons form its atomic number
They do nothing to the number of protons. They balance the charge of the protons in the nucleus.
The atomic number is equal to the number of protons in the nucleus and in a neutral atom will also equal the number of electrons.
It generally corresponds to the number of protons in its nucleus. In a neutral atom, this will also correspond to the number of electrons orbiting the nucleus; however, electrons are more likely to move around.
