This is the only option that correctly describe characterisitics of noble gases.

All noble gases have a unique atomic fingerprint.

All noble gases have valence shells with 8 electrons but Heilum has only 2 valence electrons.

Answer:

D. It is converted into kinetic energy.

Explanation:

When a book is dropped from a desk to the floor, the potential energy of the book is converted to kinetic energy as it falls.

Potential energy of a body is the energy due to the position of the body.
At a particular height, the potential energy is maximum.
A body with mass and moving with velocity will have kinetic energy
As the book drops through the height, to conserve energy, the potential energy is converted to kinetic energy.
