Question

Arrange the following as directed.

Increasing order of first Ionization potential: Li, Be, B

Answer 1

B>Be>Li

This is beacause boron hai 3 electron in its valence shell due to this amout of energy giving is more to remove electron soo that I. P is more in boron

Then Be it has 2 electron in its valence shell

And last lithium it has 1 electron in its valence shell,, soo that easy to remove electron, lesser the I. P
