**Understanding Bond Types: Electronegativity and Bond Classification**Electronegativity is a chemical property that describes the ability of an atom to attract electrons towards itself in a chemical bond. By comparing the electronegativities of atoms involved in a bond, we can determine whether the bond is nonpolar covalent, polar covalent, or ionic.Below is a simplified periodic table showing the electronegativities of elements. The elements are color-coded based on their electronegativity values:- Green: <1.0- Light Green: 1.0 – 1.4- Light Blue: 1.5 – 1.9- Purple: 2.0 – 2.4- Orange: 2.5 – 2.9- Red: 3.0 – 4.0Diagram of Electronegativity Values:``` 1A 2A 7A Li Be F 1.0 1.5 4.0 Na Mg Cl 0.9 1.2 3.0 K Ca Br 0.8 1.0 2.8 Rb Sr I 0.8 1.0 2.5 Cs Ba At 0.7 0.9 2.21B 2B 3A 4A 5A 6A 7A Cu Zn B C N O F 1.9 1.6 2.0 2.5 3.0 3.5 4.0 8 Standings for Standard Elements: H 2.18A ```**Bond Types:**1. **Nonpolar Covalent Bonds**: Occur when the electronegativity difference between two atoms is less than 0.5.2. **Polar Covalent Bonds**: Occur when the electronegativity difference between two atoms is between 0.5 and 1.7.3. **Ionic Bonds**: Form when the electronegativity difference between two atoms is
