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.

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
