WebBecause it is negatively charged (-1), it must have one more electron as compared to protons, thus 17 + 1 = 18 electrons. Test Yourself Determine the number of electrons in each of the following ions. Hint: Use the periodic table to first determine the number of protons based on its elemental identity. a) Mg 2+ b) Fe 3+ c) O 2- Answers WebIf you have an equal amount of protons and electrons, then you would have no charge. But in this case, we have a surplus of electrons. We have two more electrons than protons and since we have a surplus of the negative charged particles we, and we have two more, we're going to have a negative two charge and we write that as two minus.

WebThe 18-electron rule is a chemical rule of thumb used primarily for predicting and rationalizing formulas for stable transition metal complexes, especially organometallic compounds. The rule is based on the fact that the valence orbitals in the electron configuration of transition metals consist of five (n−1)d orbitals, one ns orbital, and three … WebWhen a metal complex has 18 valence electrons, it is said to have achieved the same electron configuration as the noble gas in the period, lending stability to the complex. …

WebAn ion (/ ˈ aɪ. ɒ n,-ən /) is an atom or molecule with a net electrical charge.The charge of an electron is considered to be negative by convention and this charge is equal and opposite to the charge of a proton, which is considered to be positive by convention.The net charge of an ion is not zero because its total number of electrons is unequal to its total number of … WebTherefore, the element that forms the +3 ion that has the given electron configuration is Cobalt (Co ). Why do we write the 3d sublevel after the 4s sublevel? In the electronic configuration of transition metal we first fill 4s -orbital since the energy of 4s -orbital is less than the 3d -orbital due to screening of nucleus charges.
