Question

Which is expected to be more stable 6/3Li or 9/3Li

Answer 1

6/3 Li is more stable due to it being composed of more than two stable isotopes.

Answer 2

Step-by-step explanation:

In
`^(6)_(3)Li`, the atomic number is 3 and mass number is 6. Hence, there are 3 protons and 3 neutrons in this element.

Whereas in
`^(9)_(3)Li`,the atomic number is 3 and mass number is 9. Hence, there are 3 protons and 6 neutrons.

And, it is known that for lighter elements the ration for neutron to proton should be 1:1. Whereas for heavier elements the ratio for neutron to proton should be 3:2.

Hence, in
`^(6)_(3)Li` the ratio for neutron to proton is 1:1. So, it is more stable in nature.

Thus, we can conclude that
`^(6)_(3)Li` is expected to be more stable.
