答案和解析
It's not very difficult to understand that the two chemical materials you mentioned have vital difference in the chemical bond ,which connected the two elements together.Mostly,the chemical bond determines what form a material should be.Normaly,there are two kinds of chemical bond:ironic bond and electrovalent bond.Because lithium oxide is structured by electrovalent bond,it has a high melting point.
