Examples of pure substances include tin, sulfur, diamond, water, pure sugar (sucrose), table salt (sodium chloride) and baking soda (sodium bicarbonate). Crystals, in general, are pure substances. Tin, sulfur, and diamond are examples of pure substances which are chemical elements.
Likewise, what is a non element?
In chemistry, a nonmetal (or non-metal) is a chemical element that mostly lacks metallic attributes.
What is an example of a non element?
Element non examples include all compounds, which are substances made when two different types of atoms form a chemical bond. Any material made by mixing elements is no longer an element.
What is the different between element and molecule?
Elements are pure substance consisting of only one kind of atom. A molecule can have different number of same type of atoms (ozone - 3 oxygen atoms whereas, oxygen - 2). Here I have mentioned that ozone contains oxygen atom. But ozone is a molecule (found in atmosphere) and oxygen is the element.
