What is ionazation energy?​

Answer 1

$\footnotesize \sf \blue{Ionization \: energy \: is \: the \: quantity \: of \: energy \: that \: an \: isolated,} \\ \footnotesize \sf \blue{gaseous \: atom \: in \: the \: ground \: electronic \: state \: must \: absorb \: to}\\ \footnotesize \sf \blue{discharge \: an \: electron, \: resulting \: in \: a \: cation. \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: } \\ \footnotesize \sf \blue{ H(g) \: → \: H \: + \: (g) \: + \: e− \: This \: energy \: is \: usually \: expressed}\\ \footnotesize \sf \blue{in \: \: kJ/mol, \: \: or \: \: the \: \: amount \: \: of \: \: energy \: it \: takes \:for \: all \: the \: } \\ \footnotesize \sf \blue{ atoms \: \: in \: \: a \: \: mole \: \: to \: \: lose \: \: one \: \: electron \: \: each. \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: }$
