How do ionic bonds, covalent bonds, and polar bonds differ?
Answer:
Ionic bonds do not share electrons. The give on up to satisfy the octet. (NaCl is a good example)
Covalent bonds share the electrons to satisfy the octet. (Methane is a good example)
Polar bonds have different electronegative and the one with the higher electronegativity has a stronger partial neg charge
In short, ionic bonds are electrostatic forces of attraction that exist between oppositely charged ions. Therefore, it's usually formed between metals & non-metals. NaCl (sodium chloride) is an example that has ionic bonds.
Covalent bonds are formed between atoms of non-metals, when they share electrons to form molecules. CO2 (carbon dioxide) is an example that has covalent bonds.
Polar bonds are formed between atoms of different electronegativity, & are arranged unsymmetrically such that the dipole moments do not cancel off.
