Ionic vs. Covalent Bonding Explained

The video tutorial explains the differences between ionic and covalent bonds, including polar and nonpolar covalent bonds. It uses examples like bromine (Br2), methane (CH4), and lithium fluoride (LiF) to illustrate these concepts. The tutorial also discusses electronegativity and how it affects bond polarity. Additionally, it highlights exceptions to general bonding rules, such as ammonium nitrate, which contains both ionic and covalent bonds.

What type of bond is typically formed between a metal and a non-metal?
