In ascending order, the energy shells can hold 2, 8, 18, 32, 50 and 72 electrons. The number of electrons each shell can hold is determined by the formula 2 * n^2, where n is the energy level of the shell. More »

Phosphorous has five electrons in its valence shell. Two are in the 3s orbital. The remaining three are distributed evenly among the three orthogonal 3p orbitals. More »

The number of electrons present in a given energy level depends on the element. The formula for determining the electron capacity for each energy level is "two times n squared," where n is equal to the number of the leve... More » Science Biology Cells

The valence electron configuration of Pb is [Xe] 4f14 5d10 6s2 6p2, or 2, 8, 18, 32, 18, 4 electrons per shell. It has four valence electrons in the outermost shell. Lead is placed in group 14 or p-block and Period 6 of ... More »

Nitrogen has five electrons in its valence shell. The valence shell is the outer shell of an atom, and its electrons are prone to break away from the atom and become free electrons or latch on to another atom. More »

Elements in the same group of the periodic table have similar properties because their electronic configurations have the same number of electrons in the outermost shell. Elemental behavior is almost completely reliant o... More »

A good example of the octet rule would be chlorine, which has seven electrons in its outer shell and bonds easily. Chlorine is able to bond with elements like argon so it can attain eight electrons and fulfill the octet ... More »
