How many compounds are in potassium sulfide (K2S)?
To determine the number of compounds in potassium sulfide (K2S), we first need to understand the composition of the compound.
Potassium sulfide (K2S) consists of two potassium ions (K+) and one sulfide ion (S2-). It is an ionic compound because it is formed by the transfer of electrons between potassium and sulfur.
In K2S, there is only one type of cation (potassium ion, K+) and one type of anion (sulfide ion, S2-), which means it is a binary compound.
Therefore, in the compound potassium sulfide (K2S), there is only one compound.
