WebIonisation energy across a period. The ionisation energy over a period increases due to the following factors:. Across a period the nuclear charge increases; This causes the atomic radius of the atoms to decrease, as the outer shell is pulled closer to the nucleus, so the distance between the nucleus and the outer electrons decreases; The shielding by … WebIonization energy generally increases moving from left to right across an element period (row). This is because the atomic radius generally decreases moving across a period, so there is a greater effective attraction between the negatively charged electrons and positively-charged nucleus.
