# Covalent Bonding ## Page 86 - Strong electrostatic force of attractions between nuclei & atoms. - **Covalent Bonding** - **Drawing Covalent Bonds** - Covalent bonds are drawn from **dot and cross diagrams**. - **Example:** - *H* *H* Both hydrogen nuclei are attracted to the shared pair. - **Diatomic:** Contain 2 atoms - Once elements share electrons, they - **Multiple Covalent Bonding** - The oxygen atom has 6 electrons (group 6) on its outer shell. - So, if two oxygen atoms combine, they will share 2 electrons each. - **Shell Number:** Amount of atoms shared (Period). - **Electron Number:** Amount of electrons in the outer shell (Group). - This is called a **double bond**: O=O - 2 shared pairs of electrons. ## Page 88 - **Covalent bonds** - A carbon atom is made by sharing atoms, the outer shell electrons. - So it'll form - **This is**
