imagine and write what type of ions are formed generally by an atom of element with low ionisation energy low electron affinity with high atomic size.........pls tell me
this is my exam question of today
Answers
answer : cations or electropositive ions.
ionisation energy is the amount of energy required to remove an electron from isolated gaseous atom.
if ionisation energy is low, it means atom can easily remove an electron from outmost orbit, means it has tendency to be electropositive in nature.
electron affinity is the amount of energy ejected when we add an electron in any atom in gaseous state. low electron affinity of any atom means low energy ejected when we add an electron in that atom, it is possible when atom is electropositive in nature. because this atom doesn't have tendency to be electronegative.
when we go down the group, size of atom increases and also metallic nature increases. if size of atom is large then, atom must be metallic in nature. and we know, metals have tendency to remove electrons and to be electropositive in nature.
