A chemical reaction which combines atoms of more than one element, in a configuration that is not like any existing configuration. In some cases, the chirality (left-handed twist or right-handed twist) can be enough of a difference for it to be a new compound.

In most cases,two.
Three hydroxide ions are needed to form a neutral ionic compound with an aluminum ion. Aluminum has a charge of +3, while hydroxide has a charge of -1 per ion. Therefore, the formula Al(OH)3 is needed for a neutral compound.
One chlorine atom is needed to bond with one copper II atom to form the compound copper (II) chloride (CuCl2).
Two.
They can form a new compound.
Iron rusts when it reacts with oxygen in the presence of water to form iron oxide. The compound needed for iron to rust is iron oxide, which is commonly known as rust.
New compounds can form through single replacement, double replacement, decomposition, synthesis, or combustion. Single replacement is where a compound reacts with an element and the element replaces one of the other elements within the compound. Double replacement is where a compound reacts with another compound and one element from each compound swaps places with the other element from the other compound to form brand new compounds. Synthesis is where two elements react with each other to form a compound. Decomposition is where a compound breaks into the elements that form it. Combustion is where oxygen combines with another compound to produce CO2 and H2O.
When two or more elements combine chemically, they form a compound. This occurs through the bonding of atoms to create a new substance with unique properties different from those of its individual elements.
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.
A molecule or a compound
A new compound (the product) must be obtained.
