Electronegativity Difference and Chemical Bonding
The type of chemical bond formed between two elements largely depends on their electronegativity difference. If a little or no electronegativity difference is present, the elements will form a nonpolar covalent bond and share electrons. If a larger electronegativity difference is present, the elements will either form a polar covalent bond or ionic bond.
Essential concepts: Electronegativity difference, ionic bond, polar covalent bond, nonpolar covalent bond.
