A substance made up of identical atoms is called an element. Elements are the fundamental building blocks of matter and cannot be broken down into simpler substances by chemical means. Each element is defined by its unique number of protons, known as its atomic number, and is represented on the Periodic Table. Examples include hydrogen (H), oxygen (O), and gold (Au).

How can you use Dalton's atomic theory to explain why every sample of pure substance has the same properties?
Dalton's atomic theory states that elements consist of indivisible particles called atoms and that atoms of the same element are identical in size, mass, and properties. Therefore, every sample of a pure substance will have the same properties because each sample is made up of the same type of atoms arranged in the same way.
What is the name of a substance made up of two or or atoms?
a molecule
Why is copper a pure substance?
Copper is considered a pure substance because it is made up of only one type of atom, specifically copper atoms. There are no other elements or compounds mixed with it. This makes copper chemically uniform and homogeneous throughout.
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 an?
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.
What molecules made up of two identical atoms that share the electrons equally?

What is the substance made up of atoms?
All substances are made up of atoms. Atoms are the basic building blocks of matter and are composed of protons, neutrons, and electrons. These atoms combine to form molecules, which make up different substances.

What elements have water in them?
None.An element is a pure substance, composed throughout by identical atoms, that cannot be broken down into simpler components by chemical means. Water is a compound, a substance composed of the combination of atoms of two or more elements into molecules; in this case, a molecule of water is made up of two atoms of hydrogen, and one atom of oxygen.
What is the relationship between atoms and an elements?
An element is made by atoms. smallest part of element is atom.
Are elements made up of only one atom?

What is matter composed of identical atoms?
Matter is composed of identical atoms that make up elements. These atoms can combine to form molecules through chemical bonds, which in turn create the different substances we observe in the universe. The properties of matter are determined by the type of atoms present and how they are arranged.
What is a substance made up of the combined atoms of two or more elements?
compound
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 an?
