Answer:
Step-by-step explanation:
A substance made up entirely of one kind of atom is referred to in science as a pure element. It denotes chemical homogeneity and the absence of any additional elements or compounds in the substance. Pure elements have consistent qualities that can be utilized to pinpoint the element.
Depending on the temperature and pressure, a pure element can exist in solid, liquid, or gas form. For instance, gold is a pure element that exists as a solid at room temperature, unlike oxygen, which is a pure element and exists in the atmosphere as a gas.
Separating pure elements from compounds, which are made up of two or more separate elements that are chemically bound, is crucial.
