    Ionisation energy is energy required to remove most loosely bounded electron from an isolated neutral gaseous atom. In ques 57,see 4th IE is very high means it is difficult to remove 4th electrons i.e after removal of 3 electrons it leads to stable electronic configuration. So valence electrons =3
