What are true about Lewis dot structures...

What are true about Lewis dot structures of molecules ?
Each bond is formed as a result of sharing of an electron pair between the atoms.
Each combining atom contributes one electron to the shared pair.
Octets of both the atoms get completed
Electron dot structures also known as Lewis structures of molecules.
