Lewis structure

Lewis structures are also known as electron dot structures. The diagrams are named after Gilbert N. Lewis, who described them in his 1916 article entitled The Atom and the Molecule. Lewis structures depict the bonds between atoms of a molecule as well as any unbonded electron pairs. You can draw a Lewis dot structure for any covalent molecule or coordination compound.

LEWIS STRUCTURE BASICS
A Lewis structure is a type of shorthand notation.

Atoms are written using their element symbols. Lines are drawn between atoms to indicate chemical bonds. Single lines are single bonds. Double lines are double bonds. Triple lines are triple bonds. (Sometimes pairs of dots are used instead of lines, but this is uncommon.) Dots are drawn next to atoms to show unbonded electrons. A pair of dots is a pair of excess electrons. https://www.thoughtco.com/lewstructures-or-electron-dot-structures-607566
