The Sulfhydryl group is much like the Hydroxyl in that a Group 16 Elements have 6 outer shell electrons and have a tendency to form two covalent bonds. Whereas ionic compounds are usually formed when a metal and a nonmetal combine, covalent compounds are usually formed by a combination of nonmetals. There is one Nickel ion at unknown charge "x". Our electronegativity calculator is here to help you with your chemistry questions related to bonds between atoms. S2F10: disulfur decafluoride : H2O: dihydrogen monoxide: water : H2S: dihydrogen monosulfide: hydrogen sulfide: NH3 : nitrogen trihydride . Remember, prefixes are NOT used for ionic compounds. Is CH4O an ionic compound or covalent compound? What is the correct formula of phosphorus trichloride? There is no sUch compound Related questions Name of S2F10? What is the compound S2F10?

Thus, the compound formed from sodium and chlorine will be ionic (a metal and a non-metal). Nonmetal atoms in polyatomic ions are joined by covalent bonds, but the ion as a whole participates in ionic bonding. Advertisement. Legal.
