No. An element is a pure substance made of only one kind of atom. A compound is a pure substance made of two or more kinds of atom.
A pure substance is a substance that is consistent throughout; it only has one substance. Example: pure sugar has only sugar throughout. Because of this, there could be any atoms in a pure substance, but those atoms would be in definite proportions.
A compound is still a type of pure substance because of its number of particles. In order to be a pure substance, something needs one particle, and even though a compound is made of multiple elements, it still has a single particle.
Salt on its own is a pure substance. It consists entirely of sodium chloride ions. On the other hand, pepper is not a pure substance. It is a mixture of many different substances.
Pure Substance.Hg stands for mercury. A pure substance is made of only one type of atom or molecule. Since mercury is an element, it is a pure substance.
If you state what something is made of, and it is made entirely and only of that substance which you have stated, then the definition of purity is satisfied. Therefore a pure substance can be made of anything, as long as it is made only of that thing. For example, a pile of garbage could be described as pure garbage as long as it contains only garbage and nothing else.

A pure substance is the same throughout. When a substance is 100% something it is pure.
Mixture
This is an element.
A pure substance is something that is only composed of one component. So, everything in the periodic table as well as every single molecule can be considered a pure substance. For example, a block of sulfur is a pure substance because it's made entirely out of sulfur. Another example would be a cup of pure acetone because there is only acetone inside the cup. So, salt water is not a pure substance because it's water mixed with salt.
A pure compound is made up entirely of one substance that has a single chemical property. A mixture is made up of two or more pure compounds with distinct chemical properties.
A substance made entirely of one type of molecule and crystal structure. Sugar, common salt, and sulphur would all be good examples.

Iron is an element, so it is a pure substance.
Gelatin is a protein made from animal products. It is a mixture not a pure substance
