WebIonisation energy decreases down a group. Ionisation energy increases across a period. Ionisation energy increases across a period due to increasing nuclear charge. This increases the attraction between the nucleus and the outermost electron. Take carbon and boron, for example. WebThis is because nuclear charge increases and atomic radius decreases, but the number of inner shielding electron shells remains the same. Overall, there is a stronger attraction between the outermost electron and the nucleus, making it harder to remove it. First ionisation energy down a group. Ionisation energy decreases down a group.

WebCorrect option is A) Generally, the atomic radius decreases across a period from left to right and increases down a given group. Moving from left to right across a period, electrons are added one at a time to the outer energy shell. Since the number of protons is also increasing, the effective nuclear charge increases across a period. Web9 nov. 2024 · The atomic radius of main-group elements generally increases down a group because effective nuclear charge increases down. So, option (D) is correct. What is atomic radius?
