The

Energy is absorbed and then released to form an emission line

Explanation:

In general, the atom consists of nuclei which contains protons (positive charge) and neutrons (neutral charge), and there are electrons (negative charge) which orbit in certain orbits at a certain discrete set of distances from the nucleus. These orbits called energy levels, and every level has its definite energy differs from others(these energy levels take symbols from K to Q). when the electron gain (absorb) an energy equals to the the difference energy between two energy levels, it will transfer or jump from the lowest energy level to the higher one and will be in the excited state, and then the electron can lose this energy to be more stable and go back to the lower energy level by releasing (emitting) electromagnetic radiation with a frequency ν to form an emission line, where, ΔE = E2 - E1 = h υ, where h is planck constant and υ is the frequency.

Answer from: Marqiuse412

The correct answer is option;

Energy is absorbed and then released to form an emission line.

Explanation:

Whenever an electron absorbs an energy it jumps from lower energy state to higher energy state.

When an electron jumps from higher energy level to lower energy level it emits out an energy in the firm of the electromagnetic radiation.This release in energy can be visualized by taking spectra where emission line will observed.

So, when an electron move from second energy level to third energy level which means energy was absorbed by an electron.

After that when electron came back to second energy level again energy was released as electromagnetic wave radiation which can be seen as emission line.
