Question

[02.06]When electrons are in an unstable state, they will quickly return to their lower energy level. When this happens, energy will be released. What conditions are the electrons in before this energy is released?
electromagnetic



excited state



ground state



quantized

Answer 1

The lowest energy state an atom can be at is called its ground state. When an electron in an atom has absorbed energy it is said to be in an excited state. An excited atom is unstable and tends to rearrange itself to return to its lowest energy state. When this happens, the electrons lose some or all of the excess energy by emitting light. Light is only emitted at certain frequencies, each corresponding to a particular electronic transition within the allowed states.

electrons emitting light so the electrons will be in ground state

Answer 2

Answer: Excited state

Explanation:

An electron in the lowest energy state is called as ground state and is also known as stable energy level.

An electron in the upper energy state is called as excited state and is also known as unstable energy level.

Quantized energy levels are those energy levels which have fixed value of energy.

Electron tries to remain in stable state, thus, if an electron is present in the excited state, it will loose energy to attain stable energy level.

Thus, the electrons are in excited state before this energy is released.
