Question

The kinetic energy of the electron present in the ground state of li2+ ion is represented by

Answer 1

The Ground State:-

• It belongs to a mechanical system that is quantum also in nature.
• It refers to the Lowest-Energy state of any system.
• It is also called the Zero-Point.
• The energy state higher than the Ground Energy is called Excited State.

An atom of Lithium has 3 electron is its Valence Shell.

Li²⁺ is positive Lithium ion. It has lost two electrons. Now there is only 1 electron present in its valence shell.

The energy that we need to take away an electron from the outermost or valence shell is called Ionization Energy.

The required Energy of the electron present in the valence shell of Li²⁺ is 122.45 eV(electron Volts).
