Question

Explain the energy level diagram in detail.

Answer 1

Energy level diagram

• The energy level diagram shows the various discrete energy levels for an atom, ion, or molecule.
• When an atom or molecule absorbs light or colloids with another atom with sufficient energy, it moves from lower energy to a higher energy state.
• At the lowest possible energy, the atom and its electron are said to be in the ground state.
• At higher possible energy, the atom and its electron are said to be excited.
• When more than one quantum mechanical state is at the same energy they are called degenerate energy level

Information acquired from the Energy level diagram

• Type of bonding will take place with a specific element and which electrons are being used.
• Explanation of why definite elements behave in indistinguishable ways.

Energy level diagram of Hydrogen

• 
• In a hydrogen atom, an electron revolves around the nucleus at the lowest energy level.
• When energy is supplied, the electron gains energy and moves up to a higher energy level.
• The electron jumps from one energy level to the other when it loses its energy.
• A several series denotes the jumps.
• Lyman series - Electron comes to the lowest energy$(\mathrm{n}=1)$
• In the Lyman series the wavelength of light stays in the UV region.
• Balmer series - Electron get down to $\mathrm{n}=2$ from an excited state.
• In the Balmer series the wavelength of light stays in the Visible Region.
• Paschen series - Electron get down to $\mathrm{n}=3$ from an excited state.
• In the Paschen series the wavelength of light stays in the Infrared Region.
