What Is the Orbital Notation for Beryllium?

The orbital notation for the element beryllium is 1s(2), 2s(2), where the parentheses represent superscript. Orbital notation is a way of representing the electron configuration of an element. In terms of configuration, this means that two electrons fill the first energy level, with another two electrons in the second level.

Beryllium is an alkaloid earth metal with many beneficial properties. It has a high hardness, despite a fairly low density, thermal conductivity and stability, and is easily bonded with other elements. The ease with which it bonds with other elements to form alloys, as well as its thermal properties, is largely due to the orbital arrangement of its electrons.
