What Atoms that don't have a full octet?

Atoms that don't have a full octet are typically those that have fewer than eight electrons in their outer shell, which can make them more reactive. Examples include hydrogen, lithium, and beryllium, which can form bonds to achieve a stable electron configuration. Additionally, elements like boron may also have incomplete octets, often forming compounds where they share electrons with other atoms. These atoms tend to seek additional electrons through chemical bonding to reach a more stable state.
