There are 6 protons in an atom, 6 neutrons, but how many electrons? Why?

An atom is a neutral particle. This means that the number of protons and the number of electrons are equal to “balance” the charge on the atom. At the same time, the number of neutrons depends on the mass of the atom, and the number of neutrons does not affect the charge of the atom. Hence e = p = 6.
Answer: 6 electrons.
