What happens when stuff dissolves I mean like what happens to the atoms and molecules then make it up I want to talk about two things here that you dissolve all the time salt and sugar these two things look very similar they're both like what kind of white powder is made up of little grains and you can pour both them into water and stir around and you see the grains get smaller and smaller and maybe break apart until eventually they've totally disappeared they've completely dissolved in the water that's what you see with the naked eye but if you had atomic vision and you can see the atoms that make up salt and sugar what would it look like as these grains broke apart and became invisible that's what we're going to talk about here so it actually depends whether something is an ionic or a covalent compound it depends on what it would look like when it dissolves so over here we have salt and this is an ionic compound this is what a grain of salt would look like and it's made of sodium ions na+ which are metals and Cl chloride ions these blue things here which are nonmetals so salt is an ionic compound made of metals and nonmetals sugar on the other hand is a covalent compound because it's made of nonmetals carbon oxygen and hydrand these nonmetal atoms are connected together into a molecule so a grain of sugar would look like this it would be a bunch of these sugar molecules all kind of lumped together notice that a grain of sugar is a lot more messy it's not nearly as well organized as an ionic compound this grain of salt over here anyway let's look at what would happen...
