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.

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
