In general, there is no maximum or minimum limit to the number of elements that can be combined in a substance. Substances can contain a single element (e.g., pure gold) or multiple elements combined in various ratios (e.g., water, which is made up of hydrogen and oxygen). The properties of a substance are determined by the types and proportions of elements present.
If matter is made up of two or more elements and has the same ratio of atoms no matter the amount of the substance, it is a compound. A compound is a substance composed of two or more elements chemically bonded together in a fixed ratio.
To answer this, we simply need to consider the lightest of the chemical elements, hydrogen. Hydrogen's atomic number, and thus its number of protons and electrons, is 1. So, by necessity, that is the minimum amount of valence electrons an atom can have.
A mixture consists of two or more substances that are physically combined, where each substance retains its individual properties. Mixtures can be separated by physical methods, such as filtration or evaporation, due to the different properties of the components. Unlike compounds, mixtures do not have a fixed composition and can vary in the amount of each substance present.
The mass of a substance does not change when the amount of the substance changes. The temperature of a substance does not change when the amount of the substance changes. However, the volume of a substance may change when the amount of the substance changes, depending on the conditions.
Ye.. the concentration of a substance is measured as the amount of substance per unit volume. Accordingly, the amount of a substance in per unit volume is the concentration of the substance.

A formula unit can also be referred to a mole unit. A mole or formula unit is the smallest amount of a substance that contains all the atoms or elements of a substance.
The energy barrier is the minimum amount of energy required for a chemical reaction to occur. Ignition temperature is the minimum temperature at which a substance will ignite and sustain combustion. The energy barrier must be overcome for the substance to reach its ignition temperature and undergo combustion.
The amount of material in a substance is mass.
