So far we use six, seven, eight, nine ten electrons three years too for P So ten plus two more is twelve and then we'LL add it'LL six MORE to give us eighteen We can confirm this by looking at chlorine in the periodic table and know that I've had one more electron. 2015-02-26 · The electron configuration of an atom describes the orbitals occupied by electrons on the atom. The basis of this prediction is a rule known as the Aufbau principle, which assumes that electrons are added to an atom, one at a time, starting with the lowest energy orbital, until all of the electrons have been placed in an appropriate orbital. 2018-02-05 · Find your atom in the ADOMAH table.
