Have you ever stopped to notice how many chemistry terms are used in everyday speech? Consider this short passage:

Their chemistry was obvious the moment they met. A small comment acted as a catalyst, starting a chain reaction of laughter and conversation.

Answer key 🔑

Their chemistry was obvious the moment they met. A small comment acted as a catalyst, starting a chain reaction of laughter and conversation.

1. chemistry (informal) – a quality that exists when two people understand and are attracted to each other (common collocations: sexual chemistry, right chemistry, personal chemistry between people)
2. catalyst (for something – a person or thing that causes a change (common collocations: to be seen as a catalyst, to act as a catalyst)
3. chain reaction – a series of events, each of which causes the next (common collocations: to start, set off a chain reaction)

It may never occur to most of us, but some of the very common words we use on an almost daily basis originate in the field of chemistry. Here are just a few examples: reaction, as in “What was her reaction to the news?”; solution, as in “Have you found a solution to the problem?”; concentration, as in “How do you maintain concentration amidst all the distractions?”; balance, as in “How do you find balance between work and life?”; and toxic, as in “When you are in a toxic relationship, things can get nasty.” Other notable examples include pressure, basic, reactive, organic, solid, bond, and element, among many others. In this post, however, we’ll focus on something slightly less common yet very practical. Read the text below for context.
