who know how to explain chemical proprieties of covalent and ionic within the bonds depict mentioned?

i have no idea about you just asked but i know that ionic bonds have high melting points and conduct electricity well when they are mixed in solutions, and they're a bond between a non metal and a metal. covalent bonds have fairly low melting points, do not conduct electricity at all and they are bonds between non metals. so if you see O2 its a covalent bond because elements form covalent bonds
