There are three different types of bonds, each seperated by their different characteristics. The types of bonds are as follows: Ionic, Covalent, and Metallic.
Ionic
- Occur between metals and nonmetals
- Occurs when one atom gains a valence electron from another
- Forms a negative ion and a positive ion
- Opposite charges attract forming an Ionic Bond
- Soluble in water and other polar solvents
- High melting points
- Conduct electricity
- Examples: Sodium Chloride, Calcium Sulfide, Magnesium Oxide
Covalent
- Occurs between nonmetals
- Both nonmetals want to gain electrons
- Electrons are shared to fill the orbital
- Low melting points
- Molecules not strongly attracted
- Polar Covalent- electrons unequally shared
- Examples: Hydrogen and Oxygen
Metallic
- Occurs between metals
- Valence electrons shared
- Valence electrons move freely
- Held together by inner forces of attraction
- Conduct electricity
- Ductile and Malleable
- Examples: Zinc and Copper
