Question
which type of compound will break apart into individual atoms when dissolved in water?
covalent
ionic
rewatch
Ionic compounds are made of ions. When dissolved in water, the polar water molecules interact with the ions in the ionic compound. The positive end of the water molecules (hydrogen) is attracted to the negative ions (anions) in the ionic compound, and the negative end of the water molecules (oxygen) is attracted to the positive ions (cations) in the ionic compound. This interaction overcomes the ionic bonds in the compound, causing the ionic compound to dissociate into its individual ions (which are atoms or groups of atoms with a charge). Covalent compounds, on the other hand, are made of atoms that share electrons. The bonds in covalent compounds are not easily broken by the interaction with water molecules in the same way as ionic bonds. So, ionic compounds break apart into individual ions (which are related to individual atoms in terms of their elemental composition) when dissolved in water.
