1. Bonding

2. Atomic Stability Atoms combine when the compound formed id more stable than the separate atoms. Atoms combine when the compound formed id more stable than the separate atoms. The only group that seldom forms compounds is the noble gases (group 18). This is true because compounds of these atoms are almost always less stable than the original atom. The only group that seldom forms compounds is the noble gases (group 18). This is true because compounds of these atoms are almost always less stable than the original atom. Atoms with a partially stable outer energy level can lose, gain, or share electrons to obtain a stable outer energy level. Atoms with a partially stable outer energy level can lose, gain, or share electrons to obtain a stable outer energy level.

3. Chemical Bond When atoms gain, lose, or share electrons, an attraction forms between the atoms, pulling them together to form a compound. When atoms gain, lose, or share electrons, an attraction forms between the atoms, pulling them together to form a compound. This attraction is called a chemical bond. This attraction is called a chemical bond. Chemical Bond- is the force that holds atoms together in a compound. Chemical Bond- is the force that holds atoms together in a compound.

4. Ionic Bonding A transfer of electrons takes place. A transfer of electrons takes place. One atoms gives electrons and the other takes. One atoms gives electrons and the other takes. Elements of different kinds usually form ionic bonds, Ex. Metals bonding with nonmetals. Elements of different kinds usually form ionic bonds, Ex. Metals bonding with nonmetals.

5. Covalent Bonding A bond between atoms that share electrons. A bond between atoms that share electrons. Usually formed between atoms of the same kind. Ex. Metals bonding with metals. Usually formed between atoms of the same kind. Ex. Metals bonding with metals.
