Many elements can form ionic and covalent bonds.With metals the non metals generally form ionic bonds- but with other non-metals they form covalent bonds.
Examples:-
The halogens (group 17) are covalent diatomic molecules, e.g. F2, Cl2 but generally form ionic compounds with metals .
Oxygen forms ions, O2- in metallic oxides but bonds covalently to hydrogen in water nitrogen in ammonia, sulfur in H2S etc
hydrogen forms the hydride ion in compounds such as LiH but bonds covalently in water and when bonded to carbon
nitrogen forms the N3- ion in compounds such as Li3N but bonds covalently with oxygen in nitrogen dioxide.
Covalent bonds are usually between a non-metal and another non-metal. Ionic bonds are usually between a metal and a non-metal. Since gold is a metal it will make ionic bonds not covalent.
stable
The bonds between nitrogen and hydrogen are covalent. They make several compounds including ammonia and hydrazine.
Ionic. BUT because of Fajans rules silver salts have significant covalent character which expalins the low solubility of silver chloride.
pretty much all are covalent bonds, C-C is covalent bond, C-H, C-O, C=C, C~C, C-N, C=N, C~N are all covalent bonds. Most polymers have just a carbon backbone, thus covalent. I can not think of an ionic bonded polymer, some of the regents used to make polymers can be ionic like salts, but the final chain of mers is covalent, typically non-polar.
Carbon typically forms covalent bonds. It is rare for it to form ionic bonds.
metallic, ionic, and covalent bonds
A covalent bond does not have oxygen in it but ionic bonds do and because Boron cannot join with oxygen it can only make covalent bonds hope that helps =)
Mendelevium can make ionic bonds.
Hydrogen bonds with hydrogen bond acceptor atoms such as Oxygen. Covalent bonds with nearly anything.
Not at all, in a covalent bond there is no losing or gaing of electrons as both of the atom reacting to make a covalent bond needs electrong therefore they share the electrons to stablized, but in ionic compound like NaCl, there is a losing of electron and gaining of electrons, therefore one element loses and one element gains. Ionic bond or "electrovalent bond" are strong bonds as compare to covalent bonds.
Covalent bonds are usually between a non-metal and another non-metal. Ionic bonds are usually between a metal and a non-metal. Since gold is a metal it will make ionic bonds not covalent.

It would form an ionic bond. The atom with 7 electrons is cation and the atom with 1 is an anion.
