This is a beautiful hand blown glass depiction of a Lithium atom.
Lithium (Li). Diagram of the nuclear composition, electron configuration, chemical data, and valence orbitals of an atom of lithium-7 (atomic number: 3), the most common isotope of the element lithium. The nucleus consists of 3 protons (red) and 4 neutrons (White, Tan). Three electrons (light blue) include a relatively unstable electron in the outer shell (ring). The stability of an element's outer (valence) electrons determines its chemical and physical properties. Lithium is an alkali metal in group 1, period 2, and the s-block of the periodic table. It is a soft reactive metal that is less dense than water, melting at 180 degrees Celsius.
Anyone would be very happy with the detail of this amazing piece.
