no nonmetals and metals cannot form covalent bonds because covalent bonding refers to the electron being shared. Because metals want to lose their electrons and sharing would just make them unstable they cannot form covalent bonds. Ionic bonds are where the electrons are transferred and this makes more sense for metals because when they lose the electrons and go into a stable state.

Abigayle Originally Answered: How do I use roman numerals when naming transition metals in compounds?
These roman numerals are used to specify the oxidation state, or charge of that atom. This means that Fe(II) is the same as Fe2+, which means that the Fe atom has lost 2 electrons, leaving it with a positive charge of 2+. This is important to know in order to balance compounds and do reactions. For example, if someone says "what is the formula for iron (II) nitrate?", I can see that the charge on iron, Fe, is 2+ because of the II in parenthesis. I know that nitrate, NO3- has a charge of -1, so I need 2 nitrates for every iron in order to cancel the charge. Therefor, iron (II) nitrate is Fe(NO3)2. Alternatively, if I see the compound Fe(NO3)2, I can figure out the name by knowing that since N03- has a negative charge, and there are 2 of them, together they have a charge of -2, so I need a charge of +2 to cancel it out. Therefore, iron, Fe, has a charge (oxidation state) of 2+, and so it is written as Iron (II) Nitrate. The same goes if it has a charge/oxidation state of 3, it is written and Iron (III). Hope this helps!

No. Covalent bonds only occur between non-metal and non-metal elements. When metals and non-metals form bonds the type of bonds are referred to as ionic bonds. Covalent bonds occur between non-metals sharing electrons to satisfy their needs in maintaining a stable outer shell of 8 electrons. If you want to look further into covalent bonds i would google van der waals forces. Yes the below answer is correct. But at your level i believe you don't need to get that technical. Highschool chemistry and university chemistry is very different. If you want the technical answer go with Casey but for the basics and foundations i dont believe you need to know that much.

depending on what metals you are referring to. The above answer is neglecting the fact that transition metals can form coordinate covalent bonds with ligands (anything with a lone pair of electrons).

The difference in the electronegativity of Magnesium and that of Hydrogen is only 0.8. Doesn t this technically make it a covalent bond?

Livy Originally Answered: How are the molecules in metals set up?
The conventional description of metals is the "electron sea" model. That is where there are positive metal ions surrounded by a sea of mobile electrons. That picture is rapidly changing. A more modern picture of metallic bonding suggests that there is a regular arrangement of metal atoms in which the bonds are covalent. The metal atoms's orbitals containing the valence electrons are overlapping in delocalized bonds. This allows electrons to easily move from one atom to the next. It also accounts for the fact that the metal atoms can move relative to each other allowing metals to be both malleable and ductile.
