Key examples include silicon, important in electronics; boron, used in heat-resistant glass; arsenic, known for toxicity and reduced use in pesticides; and antimony, which strengthens lead mixtures and is vital for electronic applications. The unique characteristics of metalloids allow them to fulfill diverse roles across various industries.

There are also exceptions to the rules. You pay less tax if you are married and/or have children. There are certain limits on how much money you can make before paying taxes. The rule is that you pay taxes, but there are also exceptions based on your personal situation. The bonding rules for molecules are generally applicable, but there are some exceptions allowed.
