Can you give one example of Yttrium in the excited state?

Yttrium is one of the elements of the periodic table with an atomic number of 39 (2 – 8 – 18 – 9 – 2) which is the ground state. It is a transition metal; it belongs to group 3 elements of the periodic table. Yttrium has a bright, silvery surface like most metals. The ground state of an element is a state where by all the shells of the element to the left are full.

At this state, the total energy of the electrons cannot be lowered by transferring one or more electrons to different orbitals. An excited state means the valence electron has moved from its ground state orbital to some higher energy orbital.

The element of Yttrium is a grayish-white rare metal, and it appears on the Periodic Table of Elements, and its symbol is "Y." Yttrium has 39 electrons and a shell structure of 2-8-18-9-2.

A term in quantum physics, the excited state is when an atom, molecule, or nucleus has more energy than its ground state. This is caused by the absorption of energy by the outermost electrons, which causes the electrons to jump to higher energy shells. The lifetime of a system in an excited state is usually short.
