Covalent Bonding

Question 1

What is covalent bonding?

Answer 1

Sharing electrons. Atoms only share electrons in their outer shells (highest energy levels). Having a full outer shell gives them the structure of a noble gas. Each covalent bond provides one extra shared electron for each atom. Covalent bonds are a shared pare of electrons. Each atom has to make enough covalent bonds to fill up its outer shell.
