Nazli Ahmedにより
1. Types of Bonds
1.1. Ionic Bond
1.1.1. formed by transferring of electrons
1.1.2. between metals and non metals ... Na and Cl
1.1.2.1. EN difference is greater than 2.0
1.1.3. forms Ionic Compounds
1.2. Covalent Bond
1.2.1. formed by sharing of electrons
1.2.2. between non-metals and non-metals
1.2.2.1. Polar Covalent Bond ... H and O
1.2.2.1.1. EN difference is between 0.5 and 1.6
1.2.2.2. Non-polar Covalent Bond ... O and O
1.2.2.2.1. EN difference is almost the same or less than 0.5

2. Chemical Bond is the electrostatic attractive force between atoms of elements holding them together
2.1. Bonds help form compounds
2.2. Bonds make atoms act as one single unit
2.3. Can be created by two ways
