A pure substance in which all the atoms have the same atomic number or number of protons is an element.
What is a pure substance all the atoms have the same atomic number or number of protons?

What does it mean when something is a pure substance?
A pure substance is an element or a compound. In the case of an element, it is composed of all the same kind of atoms. In the case of a compound, the atoms of the elements are chemically bonded in definite proportions, meaning that all samples of the same compound are chemically the samel.
Are the elements on the periodic table a pure substance?
No, as made obvious by the question itself - an element cannot "contain 2 or mroe elements"; that would defy the point of it being a single and unique element. A pure substance containing two or more elements would have to be a pure compound, and good examples are water, hydrochloric acid, ammonia and carbon dioxide.
What is a characteristic of pure substance?
A pure substance contains only one chemical identity, e.g. one element or one compound. While the properties of any pure substance might be completely different from that of another, the properties of any sample of a single pure substance will always be the same.
What is a pure substance that has all particles the same?
An element.
What is a pure sample of atoms that are all the same known as?
a element is a pure substance

A pure substance in which all the atoms have the same atomic number or number of protons is an element.
If a substance is an element is it a pure substance or a mixture?
There are two ways to think about this. Chemically, the element is a pure substance (each atom has the same number of protons). Nuclear speaking, the element may be represented by a number of different isotopes (different number of neutrons).
Substance in which all atoms are alike?

What is a pure substance all the atoms have the same atomic number or number of protons?

Can you convert a mixture to a pure substance?
Only if it is a compound, as a compound is a pure substance that can be broken down into simpler pure substances by chemicalmeans. The decomposition of a substance is a chemical process that breaks down a compound into simpler substances or its constituent elements. So, by definition, the answer is yes. However, if the pure substance was an element, the answer would be no. An element is a pure substance that cannot be broken down into any simpler substances by chemical means. It is a pure substance in which every atom present has the same atomic number.
What is a pure substance composed of atoms with the same number of protons and cant be broken down?
A chemical element.
