![]() Explanation of values: Calcium has 10 electrons that are considered inner core, n-2 or lower in energy.It is a general rule that for elements on the left in the periodic table, which have one, two, or three electrons in their valence shells. The reason for the high ionization energies of core electrons is largely that these electrons lie much closer to the nucleus than do the valence electrons, and thus they are gripped by it much more strongly.Have you registered for the PRE-JEE MAIN PRE-AIPMT 2016? Paper by Super 30 Aakash Institute, powered by embibe analysis.Improve your score by 22% minimum while there is still time.Calculate the effective nuclear charge on a valence electron in a bromine atom. The Zeff is affected by the type of orbital an electron occupies, the number of core electrons, and the number of valence electrons.Stoichiometry of a precipitation reaction course hero
