Teaching ionic and covalent compounds, and one of the differences is that some ionic compounds will dissociate when dissolved but covalent compounds usually do not (salt water vs. sugar water, just basic stuff).
Although I'm taking a very basic approach, I would still like to use proper scientific language with my students. Is there a single-word synonym for "stay bonded" or a single-word antonym for "dissociate"? My own searches either come up with only 2-word terms or with synonyms for "come together" which aren't appropriate since the atoms are already together before dissolution.
Example sentence: Some ionic compounds dissociate when dissolved, but covalent compounds __ (stay together/don't dissociate) __.
