Web•Increases down a group because valence electrons are in orbitals that extend further from the nucleus. • Decreases from left to right because electrons are held closer to the nucleus by the increasingly greater effective nuclear charge (Z eff).-Shielding by inner electrons decreases the nuclear charge felt on an electron-Valence electrons do not shield as … WebOct 11, 2024 · The electron affinity also does not follow the trend from group 1 to 2, and 14 to 15, because the gain of an additional electron results in a less stable or more unfavorable electron configuration ... WebElectron affinity increases across a period from left to right and decreased on going down the group. Since A is on the right side of B, therefore its electron affinity is higher than B; Part 3: Atomic size:-Atomic size basically refers to the radius of the atom. It increases down the group. Across a period, generally, the atomic radius decreases. god\u0027s greatness is unsearchable

Why does electron affinity decrease with increase in size

Electron Affinity Trend - Science Trends

WebJan 30, 2024 · Electron affinity increases upward for the groups and from left to right across periods of a periodic table because the electrons added to energy levels become closer to the nucleus, thus a stronger attraction between the nucleus and its electrons.

WebOn the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you move down a group. As a result, the most electronegative elements are found on the top right of the periodic table, while the least electronegative elements are found on the bottom left. Created by Sal Khan. Sort by: WebMar 4, 2024 · 1. It is generally true that the electron affinity becomes less exothermic down a group, because of the increase in atomic radius. There is a well-known exception that the electron affinity of Cl is more …

WebThe electron affinity of inert gases is zero due to their stable electronic configuration. (c) He Ionisation energy decreases with an increase in the atomic size, so it decreases as one moves down a group. Then in that … WebApr 8, 2024 · Across a period, the electron affinity increases as nuclear charge increases. Down the group, it decreases, as the nuclear charge decreases. Fluorine has the highest electronegativity and noble gasses are not included in this. The reason being they have a full valence shell and thus can neither gain nor lose electrons. 6. Shielding Effect

WebAug 10, 2024 · Electron affinity decreases moving down a group because a new electron would be further from the nucleus of a large atom. Electronegativity Electronegativity is a measure of the attraction of an atom for the electrons in a chemical bond. The higher the electronegativity of an atom, the greater its attraction for bonding electrons. WebElectronegativity decreases as we move down the group because as we move down the group, the atomic size increases and the effective nuclear charge decreases. Therefore, the tendency to attract shared pairs of …
