If the energy needed to remove the 1st, ...

If the energy needed to remove the 1st, 2nd and 3rd valence electron from an atom is V, 2V and 3V then the energy required to remove all three in one step will be xV. What is numerical value of x ?

Text Solution

Verified by Experts

The correct Answer is:
3
`A overset(v)(to) A^(+) overset(v)(to) A^(2+) overset(v)(to)A^(3+) A overset(3v)(to)A^(3+) , x = 3`
