1. Types of Chemical Bonds

2. Why do atoms bond? Atoms bond to reach stability or to reach the octet state; have 8 electrons on their valence shell ( outermost energy level) Atoms bond to reach stability or to reach the octet state; have 8 electrons on their valence shell ( outermost energy level)

3. How do atoms bond?bond Atoms bond by gaining, sharing, or losing electrons in order to have a filled outermost energy level containing 8 valence electrons.

4. What happens during ionic bonding? Atoms tend to lose or gain electron(s). Atoms that lose electron(s) form positive ions or cation. Atoms that gain electron(s) form negative ion or anion. When two charged ions bond they form a neutral compound. Atoms tend to lose or gain electron(s). Atoms that lose electron(s) form positive ions or cation. Atoms that gain electron(s) form negative ion or anion. When two charged ions bond they form a neutral compound.

5. Metals tend to lose electrons since they have few electron(s) in the outermost shell. Non metals tend to gain electon(s) to reach stability since they have many electrons in the outer most shell.

6. What happens during covalent bonding? Two atoms share their valence electron(s) in order they both reach the octet state; reach stability. When two atoms of the same element bond by covalent bond, they form a neutral group called a molecule. Ex: two oxygen atoms unite to form an oxygen molecule. Two atoms share their valence electron(s) in order they both reach the octet state; reach stability. When two atoms of the same element bond by covalent bond, they form a neutral group called a molecule. Ex: two oxygen atoms unite to form an oxygen molecule.
