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

Explanation:

In , the atomic number is 3 and mass number is 6. Hence, there are 3 protons and 3 neutrons in this element.

Whereas in ,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 the ratio for neutron to proton is 1:1. So, it is more stable in nature.

Thus, we can conclude that is expected to be more stable.

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper
