What term is used to describe the lowest energy level of a particle?

photon

excited state

ground state

emission spectrum

Ground state

Explanation:

Ground state is the lowest energy level of particle. In this state toms are stable.

When transition occur from lower energy level to higher energy level require a gain of energy. Electron could not jump into higher energy level without gaining thew energy.

When electron jump into lower energy level from high energy level it loses the energy.

The process is called excitation and de-excitation.

Excitation:

When the energy is provided to the atom the electrons by absorbing the energy jump to the higher energy levels. This process is called excitation. The amount of energy absorbed by the electron is exactly equal to the energy difference of orbits.

De-excitation:

When the excited electron fall back to the lower energy levels the energy is released in the form of radiations. this energy is exactly equal to the energy difference between the orbits. The characteristics bright colors are due to the these emitted radiations. These emitted radiations can be seen if they are fall in the visible region of spectrum.

The term used to describe the lowest energy level of a particle is ground state.

Explanation:

An atom does not react when it has a ground state configuration. All the chemical reactions take place so that the atom gets to the ground state electronic configuration.

Whenever an electron is in an excited state, it will always try to come back to its ground or we can say stable state. The most basic definition of a photon is that its a constituent particle of light. Millions of photons make up a light ray. Emission spectrum is a spectrum of elecctromagnetic radiation.

girl imma just put my comment here because i need a couple point okurrttt
