Diborane and Chemical Nomenclature

The video tutorial explains how to write the chemical formula for diboron hexahydride, also known as diborane. It begins by identifying boron and hydrogen on the periodic table, noting that boron is a metalloid and hydrogen is a non-metal. The tutorial explains that when a metalloid and a non-metal form a compound, it is considered molecular, and prefixes are used to determine the number of atoms. The prefix 'di' indicates two boron atoms, and 'hexa' indicates six hydrogen atoms, resulting in the formula B2H6. The video concludes with a recap of the formula derivation.
