Molecularity is the number of species in an elementary step. The rate law for each elementary steps follows its molecularly. For instance, the molecularity of a rate =k[A] is unimolecular and for the rate k=[A]^2 or k[A][B] is bimolecular.

molecularity is the number of reactant molecules, atoms, or ions taking part in a specified elementary reaction.

Molecularity is the number of molecules that come together to react. It is equal to the sum of the stoichiometric coefficients. (ex. unimolecular, bimolecular, etc.)

Molecularity is the number of molecules that will come together to react. If there is one it is unimolecular, two is bimolecular, and three is termolecular.

Molecularity is the number of molecules or ions that participate in the rate determining step.

Molecularity is number of particles as a reactant that participate in a reaction.
One - unimolecular
Two - bimolecular
Three - termolecular

Molecularity is the number of molecules as a reactant.
For example, N2 + O2 --> 2NO, this is a bimolecular example

Molecularity is the number of species in an elementary step meaning the number of molecules in a reaction that act as reactants.

Molecularity is how many molecules must collide for product to be formed. It relates to reaction rate because the probability of higher number of molecules all impacting at the same time is lower, and so the reaction rate will naturally be lower.

Molecularity is the amount of species that interact with each other as reactants.
