# Consider the letters in the word chemistry. Use them to make as many word "compounds" as is possible with 9 elements. How is an element different from a compound?

Interesting question...

The various permutations of valid elements from the word "chemistry" are:

• $C$
• $C e$
• $C m$
• $C s$
• $C r$
• $H$
• $H e$
• $E s$
• $E r$
• $I$
• $I r$
• $S$
• $S c$
• $S e$
• $S m$
• $S i$
• $S r$
• $T c$
• $T h$
• $T e$
• $T m$
• $T i$
• $R h$
• $R e$
• $Y$

So you have any $9$ of these at your disposal when making compounds. Let us choose the easiest elements to use: $C$, $C s$, $H$, $I$, $S$, $S e$, $S i$, $S r$, $T e$. None of those are transition metals.

These are the compounds I can think of that exist:

• $C {H}_{4}$
• $H I$
• $C s I$
• ${H}_{2} S$
• ${H}_{2} S e$
• $S i {H}_{4}$
• $S r {I}_{2}$
• $T e I$

There are probably more but anyways, you can clearly see that each of these have two different elements. That's the definition of a compound.
