Which best explains what happen when an election moves from an excited state to the ground state

When an electron moves from an excited state, kinetic energy of the electron

is high, to the ground state, kinetic energy of the electron is low, the electron

releases energy as it moves to the lower energy level. It releases some of the

energy it contains in order to match other electrons in that level.

the answer is c) abandoned properties that are contaminated with hazardous materials.

x would be the most and the least would be y because there are more fruit   and seeds than flock z has insects
