Valence comes from the Latin, meaning strength.

In Chemistry it refers to the combining strength of an element and is usually used in reference to valence electrons. Those are the outer shell electrons that form chemical bonds. In one extreme, ionic bonding, atoms either donate or accept electrons to form charged particles called ions, which are attracted to one another. In the other extreme, atoms share electrons, called co-valent bonding. You could say that they have a certain ambivalence, that is, both sides showing strength. This sharing may exhibit equivalence, as in a carbon-carbon bond, or it may show varying degrees of inequality as in the nearly balanced sulfur-selenium bond or the more extreme imbalance of a boron-oxygen bond.

Equivalence is evidently a state of affairs we desire or want to understand. A simple Wikipedia search of equivalence* lists the numerous ways we have scientific, economic, and psychological laws of equivalence and principles of equivalence in most areas of life. We have a prevalence and desire for equal or shared strength within our systems.

Furthermore, we should be discussing the seroprevalence of COVID-19 as compared to the symptom and severe symptom prevalence in our population so that we may come to a reasoned conclusion about opening our struggling economy. We lack strength as a society if we do not move forward, but continue to give in to the voices of fear, manipulation, and ambivalence.

On a more positive note, I like Valencia oranges, which were named after Valencia, Spain. That’s a strong name, but this hybrid orange was developed in California when it was still part of Mexico, by a Mexican citizen, who named it after sweet oranges in Spain.**

Thus, you have a stronger appreciation for the latent valency of the term.***
