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
The symbol for holmium on the periodic table is: Ho
Holmium's atomic mass is 164.93032.
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.
