Question

difference between absorbtion spectrum and emission spectrum ..​

Answer 1

Answer:

The structure of an atom includes a central core called a nucleus and a cloud of electrons around the nucleus. According to the modern atomic theory, these electrons are positioned in specific energy levels called shells or orbitals where their energies are quantized. The shell which is the nearest to the nucleus is known to have the lowest energy. When energy is given to an atom externally, it causes the electrons to jump from one shell to another. These movements can be used to obtain absorption and emission spectra. Both absorption and emission spectra are line spectra. The main difference between absorption and emission spectra is that absorption spectra show black colored gaps/lines whereas emission spectra show different colored lines in the spectra.
