Question

Would these two substances have an ionic, covalent, or metallic bond?

Answer 1

@Photon336

Answer 2

I see the charts @a1234 what are you asking exactly?

Answer 3

I'm supposed to tell if the substance in the fourth row in the two charts is supposed to have a ionic, covalent, or metallic bonding. It isn't very clear though because some characteristics mix.

Answer 4

Here's some background on this. well there's definitely a-lot that can be said here.

Well ionic compounds conduct electricity when dissolved in water/liquid. they are generally thought of as a strong bond because the electronegativity difference is very high between the metal and non metal, but usually electrons are transferred from the metal to the non metal.

but as solids ionic compounds have poor conductivity. Any substance that has some kind of charge in it, let's take NaCl this compound is ionic. If we put it in water, it becomes Na+ and Cl- these changes mean that it conducts electricity, and it's an electrolyte.

ionic compounds are solids at room temperature so they will have melting points, so will substances with metallic bonds. remember melting point means that the substance has to be a solid at room temperature for it to have a melting point. Covalent bonds are weaker and don't necessarily have this unless they are solids at Room temp.

Answer 5

Unknown3 cannot have a melting point as it is already a solid. So it is not an ionic compound.

Unknown2 does not conduct as a solid, so it may be an ionic compound?

Answer 6

yeah ionic compounds don't conduct electricity as a solid
