Periodic Table

Below table explains the trends in ionization potential, electron affinity and electronegativity on moving down the groups in the periodic table: Alkali Metals Group 1 [IA] Halogens Group 17 [VIIA]…

Trends in (i) Electron Affinity and (ii) Electronegativity: (a) Across a Period (Left to Right): Electron Affinity: Increases. Decreasing atomic size and increasing nuclear charge make atoms more able to…

Factors Affecting: (a) Electron Affinity: Atomic size: Smaller atoms have higher electron affinity due to stronger nuclear attraction on electrons. Nuclear charge: Higher nuclear charge increases electron affinity as the…

Ionization Potential Trends: (a) Across a Period (Left to Right): Increases Due to decreasing atomic size and increasing nuclear charge, outer electrons are more strongly held, requiring more energy to…

The factors which influence the ionization potential of an element are — Atomic size - As atomic size increases, the nuclear attraction on the outer electrons decreases and outer electron…

Trend in Atomic Radii Down Group 1 (Alkali Metals): Atomic radii increase moving down a group due to the increasing number of shells, which outweighs the effect of increased nuclear…

Factors affecting atomic size: Number of shells: More shells increase atomic size as the distance between the outermost shell and nucleus increases. Nuclear charge: Higher nuclear charge decreases atomic size…

(a) Atomic radius - It is distance between the center of the nucleus and outer most shell of the atom. (b) Ionization potential [I.P.] - It is the amount of…

Reasons for Periodicity in properties in periods and groups is as follows — Similar valence shell electronic configurations recur at definite intervals of atomic numbers. Element properties depend on the…

(a) Periodicity in properties of elements — The phenomenon of occurrence of characteristic properties of elements at definite intervals in the modern periodic table when elements are arranged in increasing order of…
