Covalent bonding

What is Covalent bonding?

Sharing of electrons

What elements react in covalent bonding?

Non - metals and non - metals

What makes covalent bonds very strong?

The positively charged nuclei of the bonded atoms are attracted to the shared pair of electrons by electrostatic forces

Why do atoms only share electrons in their outer shells?

They have the highest energy levels

Why do non - metals want a full outer shell via covalent bonds?

Electronic structure of a noble gas, which is very stable

How do you show covalent bonds?

Dot and cross diagrams

What is the displayed formula?

Shows the covalent bonds as single lines between atoms, this is showing how connected in large molecules
