WebAnother important trend is the trend in ionization energy. Ionization energy is the amount of energy required to remove an electron from an atom. As one moves from left to right across a period, the ionization energy increases. This is because the increase in nuclear charge makes it more difficult to remove an electron from the atom. WebThe trend in ionization energy across a period (for example, period 2) is explained using electrostatic forces: As you go across the period from left to right, each element contains one extra proton in the nucleus, increasing its charge. Each further element also has one extra electron in its outer shell.

Web23 nov. 2012 · Periodic trends are specific patterns starting certain elemental characteristics (ie.ionization energy) that increase or decrease as you move to a column or row.
