A main group element has the following five successive ionization energies: 1st IE: 0.58 MJ mol-1, 2nd IE: 1.52 MJ mol-1, 3rd IE: 2.75 MJ mol-1, 4th IE: 11.58 MJ mol-1, 5th IE: 14.84 MJ mol-1. Which group contains this element? Why?

Solutions

Expert Solution

it is 13 th group element or (III A group element )

explanation :

the element belongs to boron family . because first three ionisation energy values are very small differences that means the element loose three electrons easily it indicates that the element having three valence electrons .

when you coming to 4th ionisation energy the value is drastically changed the sudden jump in the ionisation represents it is very hard to remove 4th electron . so it is IIIA group element
