Did you know?
WebIonization energy (the energy associated with forming a cation) decreases down a group and mostly increases across a period because it is easier to remove an electron from a … WebThe first ionization energy of element A is defined as the energy required by an atom to form A + ions. The unit of ionization energy is given as KJ mol-1. A (g) → A + (g) + e – In the …
WebIn general, ionization energy increases across a period and decreases down a group. Across a period, effective nuclear charge increases as electron shielding remains … WebAcross a period however the ionisation energy increases. This is because there is the addition of a proton each time resulting in a higher nuclear charge due to the positive …
