What i would say: The amount of gravitational potential energy an object has depends on its height and mass. The heavier the object and the higher it is above the ground, the more gravitational potential energy it holds. Gravitational potential energy increases as weight and height increases.
Hope this helps! :)
The answer is nonmetal. good luck and give thanks :)
There can only be two electrons in the innermost shell of an atom so b is the correct answer
