Maybe take a walk on the wild side with the strange quark?

It is made up of two strange quarks and a bottom quark.

Notice that this definition gives the strange quark a strangeness of 1.

One cannot assume that under all conditions the yield of strange quarks is in thermal equilibrium.

The property that caused it to live so long was dubbed strangeness and led to the discovery of the strange quark.

Like down quarks, strange quarks have a charge of -1/3.

Antiatoms and heavy antimatter with strange quarks take top billing.

Only if many conversions occur almost simultaneously will the number of strange quarks reach the critical proportion required to achieve a lower energy state.

So, since the strange and bottom quarks have a negative charge, they have flavor quantum numbers equal to 1.

This includes the up and down quarks, and to a lesser extent the strange quark, but not any of the others.
