First ionization energy

The first ionization energy is defined as

Energy which is required to pull out one mole of the outermost shell's electrons in a neutral atom from one mole of gaseous atoms to produce 1 mole of gaseous ions each with a charge of 1+. , where A is any neutral atom.In the periodic table, Its value decreases from top to bottom in groups and increases from left to right across a particular period. Helium has the largest first ionization energy.Francium has one of the lowest.

Adozen is 12, and your needing to calculate the weight of one medium egg, so i would do 21/12=1.75 per egg, and check your answer by doing 1.75 * 12= 21 : ) : ): ): ): ) i hoped i
