Answer: what are the options?
Explanation:
Answer:
This statement is false.
Explanation:
Ionic bonds have relatively high melting and boiling points, compared to that of covalent bonds.
Ionic compounds have strong electrostatic bonds between oppositely charged ions. Covalent bonds, on the other hand, have weaker attractions between molecules.
Remember, the melting point, is simply the amount of heat (energy) it takes to break apart the molecular bonds. The stronger the bonds, the harder it will be to separate them!
Hope this helps! :)
