WebNov 14, 2024 · Electronegativity is the attractive force between the atom and the bonding electron pair. Non polar, polar and ionic bond is formed depending on the difference of electronegativity between two atoms. Electronegativity increases across the period in periodic table. Electronegativity decreases down the group in periodic table. WebAboutTranscript. 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. Sort by:
