Question

How can you type what type of solid something is? Like Na2S and CH4 and C and Cr and CaO

Answer 1

what do you mean with type of solid?
something is solid or it's not solid

Answer 2

Such as Na2S it is highly polar right. But I have to determine if it is Ionic crystal, metallic crystal, molecular solid, or covalent network solid

Answer 3

first determine if your compound has ionic bonds or covalent bonds

ionic = metal + nonmetal
covalent = 2x nonmetal or nonmetal + metalloid

Answer 4

sodium is a metal and sulfur is a nonmetal, so it's an ionic bond.
So it's an ionic crystal

Answer 5

I thought it was polar because Na is 0.9 and S is 2.5 So the electronegativety charge is 1.6 and anything between .5 and 1.7 is polar

Answer 6

That's true
