WebMar 22, 2024 · So, down the group (from top to bottom), the atomic size increases. So Electronegativity decreases. And across the period (from left to right), the atomic size decreases, so the Electronegativity increases. For electronegativity values of elements, visit Interactive periodic table. WebThe electron affinity (EA) is the energy change for the process of adding an electron to a gaseous atom to form an anion (negative ion). X ( g) + e − X − ( g) EA 1 This process can be either endothermic or exothermic, depending on the element. The EA of some of the elements is given in Figure 6.35.
Electron Affinity (Chemistry Glossary Definition) - ThoughtCo
Web(c) Electron affinity increases going down a group. (d) Electronegativity increases going down a group. Q. Electronegativity and electropositivity are two trends of the elements of the modern periodic table where: A. Electropositive character of elements decreases moving down a group. WebJul 23, 2024 · Basically, whats this means is with you dropping down a insert (period) on the table and move across a, elements follow the identical trend as sundry periods. Periodicity reflects Regular Law.

Electron Affinity Introduction to Chemistry Course Hero
WebGoing down a group, the electronegativity of atoms decreases. As you move down a group in the periodic table, atoms increase in size, with a greater number of energy levels. 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. WebTrend-wise, as one progresses from left to right across a period, the electron affinity will increase as the nuclear charge increases and the atomic size decreases resulting in a … metathorax definition
