H2 is the molecular formula of Hydrogen, a colorless, odorless, highly flammable gas. One Hydrogen atom has one electron and is the first element on the Periodic Table of Elements. The molecular polarity of H2 is linear and nonpolar.
An H2 molecule is made up of two hydrogen atoms, and they share the same electronegativity (or tendency to attract other electrons). A symmetrical molecule looks the same no matter which way you turn it or look at it, hence the name. The symmetry of a molecule affects how it reacts to light and other molecules.
It is nonpolar, because its charges are distributed symmetrically and its geometric shape is symmetrical.
Polar Molecules: 2 or more lines of symmetry when you cut through the middle of the molecule; symmetrical geometric shape and symmetrical distribution of charge!
Nonpolar Molecules: Less than 2 lines of symmetry when you cut through the middle of the molecule; asymmetrical geometric shape and asymmetrical distribution of charge!
