Number of Protons, Neutrons, and Electrons in an Atom
WebThe maximum number of electrons in an orbit is given by 2n2. According to Niels Bohr, the shells or orbits in which electrons are present in an atom are represented by K (n=1), L (n=2), M (n=3), N (n=4). The term, 'n' represents the orbit's number. So, M shell will have 2x 32 = 2 x 9 = 18 electrons. Suggest Corrections 0 Similar questions Q.

WebThe number of electrons in an electrically-neutral atom is the same as the number of protons in the nucleus. Therefore, the number of electrons in neutral atom of Oxygen is 8. Each electron is influenced by the electric fields produced by the positive nuclear charge and the other (Z – 1) negative electrons in the atom. WebMost of the elements important in biology need eight electrons in their outermost shell in order to be stable, and this rule of thumb is known as the octet rule.
