I believe you are defining an "atom".
The primary factor that determines which substance is most responsible for chemical reactions is the reactivity of the substances involved.
Elements are the primary substances that make up all matter, and they cannot be broken down into simpler substances. Molecules are combinations of two or more atoms bonded together, which can also be components of matter. Both elements and molecules play a crucial role in the composition of all things in the physical world.
Unfortunately, it is not possible to separate the primary colors from purple ink because purple is a secondary color made by combining primary colors (blue and red). Once the ink is mixed to create purple, you cannot easily extract the primary colors from it.
The primary standard used in an experiment is typically a highly pure compound that can be used to determine the concentration of another substance through titration or other analytical methods. A primary standard is defined as a substance of known purity that can be accurately weighed out to prepare a solution with a precisely known concentration.
The two kinds of homogeneous matter are solutions and pure substances. Solutions are a mixture of two or more substances that are evenly distributed at a molecular level, while pure substances are composed of only one type of element or compound.
The primary factor that determines which substance is most responsible for chemical reactions is the reactivity of the substances involved.
Secondary pollutants are the substances that pollute the air only after they interact with other substance in the Earth's environment. Primary pollutants are injected into the atmosphere directly.
A primary standard substance is referred to a reagent which is pure. This is a substance that can be weighed easily due to its purity.
Matter can be divided into two primary groups: pure substances and mixtures. Pure substances consist of a single type of particle and have consistent properties throughout, including elements and compounds. Mixtures, on the other hand, contain two or more different substances that retain their individual properties and can be separated by physical means.
A primary standard substance is referred to a reagent which is pure. This is a substance that can be weighed easily due to its purity.
Imppure matter is a substance which contains a mixture of elements- 1. It does not have fixed melting point, boiling point or density 2. t gives more than one spot whenn analysed by chromatography

The primary determing factor would be the size of the substance
