Ionisation energy across period

WebIn general, ionization energy increases across a period and decreases down a group. Across a period, effective nuclear charge increases as electron shielding remains constant. This pulls the electron cloud closer to the nucleus, strengthening the nuclear attraction to the outer-most electron, and is more difficult to remove (requires more energy). WebThe ionisation energy across a period increases due to the following factors: Across a period the nuclear charge increases The distance between the nucleus and outer electron remains reasonably constant The shielding by inner shell electrons remains the same
