Question

For chemistry lovers…

"Arrange ( Li^+ ,B^3+ ,Be^+) in order of there increasing atomic size , specially give full explaination of it ."

plzzz help …!!

Answer 1

Hii There!!!

We know that, size of an atom increases down the group as the number of shells increases ( i.e, ionic radii increases)
whereas, from left to right atomic size decreases because, ionic radii decreases.

But here, Li has +1 charge and z =3 so its value turns to z=2.

Also, B has +3 charge and z= 5 so its value turns to z = 2

Similarly, Be has +1 charge and z = 4 so its value turns to z = 3

So, there will be no increasing order...

Hence, Li^+ = B^+3 = Be+1
