That means they easily react with one another.
The more reactive substance is known as a catalyst.
well in an example sodium and chlorine make up the substance salt with is created by two toxic substances with makes sodium a reactive substance
Chemical and physical properties
A highly combustible substance is not necessarily the same as a highly reactive substance, though there can be overlap. Combustibility refers specifically to a material's ability to ignite and burn in the presence of an oxidizer, typically oxygen. In contrast, reactivity encompasses a broader range of chemical interactions, including those that may not involve combustion. Therefore, while many highly combustible substances are also reactive, not all reactive substances are combustible.
Molecule and compound are two words that mean a substance made of atoms that are bonded together.
A substance that is very very reactive (even to dust), flammable and toxic.
Not necessarily. A substance that is highly combustible has a tendency to ignite easily and burn rapidly, but it may not necessarily be highly reactive. Reactivity refers to how readily a substance undergoes a chemical reaction with other substances, which may or may not lead to combustion.
Potassium is the most reactive element with oxygen, readily reacting to form potassium oxide.
A single replacement reaction (single displacement reaction). The generic form is: A +BC-->B+AC.For example:2Al+3CuSO4-->3Cu+Al2(SO4)3The more reactive aluminum replaced the copper in the copper sulfate compound. An activity series indicates which elements will replace other elements. You can find activity series online.
reduction or oxidation example: (this isn't a real reaction) ClO + CS4 --> CO + ClS4 the chorine has been reduced, because the carbon is more reactive the carbon has been oxidised, because it is more reactive oxidation = the addition of oxygen reduction = the subtraction of oxygen

Francium is not reactive as it is a very weak and small substance of an atom in the element. Francium is used useless things, so therefore it is not reactive.
