How many electrons does an atom have

WebHow many electrons in an atom could have these sets of quantum numbers? n = 2 n = 5, f = 1 n = 6,= 2, m/ = -1 electro electrons: electrons WebThe atomic number is the number of electrons in that element. Oxygen atom electron configuration (Bohr model) The atomic number of oxygen is 8. That is, the number of electrons in oxygen is 8. Therefore, an oxygen atom will have two electrons in the first shell and six in the 2nd shell.
