The metal having low melting point
WebHere is a short list of the main properties of covalent compounds: Most covalent compounds have relatively low melting points and boiling points. Covalent compounds … WebAug 15, 2024 · Group 1 metals like sodium and potassium have relatively low melting and boiling points mainly because each atom only has one electron to contribute to the bond - but there are other problems as well: Group 1 elements are also inefficiently packed (8-coordinated), so that they aren't forming as many bonds as most metals.

WebSep 1, 2024 · Because covalent bonds are weaker than ionic bonds, covalent compounds typically have lower melting points and boiling points. Most covalent compounds are fairly soft and flexible because covalent compounds are not very rigid. Covalent compounds usually don't dissolve in water, unless they are polar compounds.
