Elements of group 18 are least reactive.These are noble gases.They are unlikely to have a reaction with any element or compound.
rubidium, magnesium, cobalt, argon.
a chemical reaction or an element
in a decomposition reaction a chemical breakes down into the elements in the compound e.g: compound = element + element
No. An atom is made of Elements. Name of element is decided by number of Protons, containing in it's Nucleus. Two or more different types of elements react with each other to form compound in what is called as chemical reaction.

All the inert gasses ie Ar, Kr, Xe, Rd, Ne, He are unlikely to have any chemical reactions with any compound or element.
a chemical reaction or an element
when different indivisual element combine to form a compound, this reaction is called combination A reaction in which a Compound is decomposed into its constituent elements is called decomposition
in a decomposition reaction a chemical breakes down into the elements in the compound e.g: compound = element + element
You can identify a single replacement reaction because the reactants are a compound + an element. The products of a single replacement reaction are found by switching the element with another element in the compound. Metals switch with metals, non-metals switch with non-metals, and the most reactive element is always in the compound. A double replacement reaction can be identified because the reactants are always compound +compound. The products would also be two compounds but the elements would switch.
ammonia and chlorine to form ammonium chlorine, 8NH3 + 3Cl2 ---> 6NH4Cl + N2
If a substance undergoes a decomposition reaction, it is a compound. Pure elements cannot decompose because there is nothing for them to decompose into.
A reaction when a free element or ion takes the place of and element or ion in a compound is called a single replacement reaction
Generally is compound; but it is not impossible that this product be an element.
Metals are elements.
