WebBoth metallic and covalent bonding can be observed in some metal samples. For example, covalently bonded gallium atoms tend to form crystal structures that are held together via metallic bonds. The … WebCrystalline materials have highly defined and repeatable arrangements of molecular chains. These materials tend to have sharp melting points. Some of the common examples are …
WebWhen two oxygen atoms bond, they become a molecule and don’t interact much with other molecules. A metallic bond behaves more like one big molecule (except that unlike diamond or graphite, it’s malleable because there aren’t technically any covalent bonds forming a specific crystal structure.)
