Electron affinity of sr
WebElectron affinity can be defined in two equivalent ways. First, as the energy that is released by adding an electron to an isolated gaseous atom. The second (reverse) definition is that electron affinity is the energy required to remove an electron from a singly charged gaseous negative ion. ... Sr: Strontium: 0.052 06(6) 5.023(6) 39: Y ...

WebSep 16, 2024 · Ionization energy (IE) is the amount of energy required to remove an electron from an atom in the gas phase: A ( g) → A + ( g) + e − Δ H ≡ I E. IE is usually expressed in kJ/mol of atoms. It is always positive because the removal of an electron always requires that energy be put in (i.e., it is endothermic).

An element's second ionization energy is the energy required to remove the outermost, or least bound, electron from a 1+ ion of the element. Because positive charge binds electrons more strongly, the second ionization energy of an element is always higher than the first. Created by Jay.
