Question

question 14 of 25
what is an energy level?

a. the energy required to remove an electron from its nucleus

b. the total energy possessed by all the electrons of an atom

c. the energy possessed by an electron at a set distance from the nucleus

d. the energy contained within the nucleus of an atom

Explanation:

• Option A describes ionization energy, not energy level.
• Option B is incorrect as energy level pertains to individual electrons' energy at specific distances, not total energy of all electrons.
• Option C: Energy level is the energy an electron has at a particular distance (orbital) from the nucleus. This matches the definition.
• Option D refers to nuclear energy (like binding energy), not electron energy levels.

Answer:

C. The energy possessed by an electron at a set distance from the nucleus
