An example isthe holmium hydroxide Ho(OH)3.
ternary compuonds are composed of three elements
carbonyl sulfide
Ternary means three different elements (binary means two). These are salts with either :-most commonly a monoatomic cation and a poly atomic anion e.g NaNO3sometimes a a polyatomic cation and monoatomic anion NH4Cl
Holmium's abreviation is Ho
Holmium is a rare earth metal.
Lithium is an element, however "Holmium" is not you may be mistaking Holmium for Helium though
Holmium's atomic mass is 164.93032.
The symbol for holmium on the periodic table is: Ho
Holmium is in the lanthanoid series.
Holmium (67 on the Periodic Table) is a shiny metallic silver colour.
The reaction you described is a metathesis reaction involving the formation of a ternary salt. Metathesis reactions involve the exchange of cations or anions between compounds. In this case, a metal oxide reacts with a nonmetal oxide to form a ternary salt compound.
A ternary compound is formed through a synthesis reaction because it involves the combination of three elements to form a new compound. The reactants and products in a synthesis reaction can include elements or compounds. In the case of a ternary compound, the three elements react together to produce the compound.
