Here are some examples:
* Bivalent: Having two valencies (referring to the number of bonds an atom can form).
* Multivalent: Having multiple valencies.
* Valence: The combining power of an atom or radical.
While the root word valent is often used in chemistry to describe the combining power of elements, it can also be used more broadly to describe something that is strong, powerful, or significant.
For example, you might say that a person has a valent personality, meaning they are strong and influential.
