Respond to: When two atoms with various electronegativity are joined to one another by covalent bond, the shared electron pair will never from the centre as a result of variance in electronegativity. Such as, in hydrogen flouride molecule, flouride has higher electronegativity than hydrogen.
Atomic sizing. With the increase in atomic size, the volume of electron shells raises and therefore the power of attraction amongst the electrons and also the nucleus decreases. Consequently the ionization enthalpy decreases.
