Such a substance is always an element.
Fermion
John Dalton proposed the atom theory in the early 19th century. He suggested that all matter is made up of tiny, indivisible particles called atoms, and that all atoms of a specific element are identical in size, mass, and properties.
Basically everything and anything that is matter is composed of atoms. This would mean that literally, everything, in a classroom is made of atoms.
Matter is composed of atoms, which are the smallest units of matter. Atoms consist of a nucleus made up of protons and neutrons, surrounded by a cloud of electrons.
Most matter doesn't exist as individual atoms. Inert or "noble" gasses like helium and argon excepted, most matter exists in molecules that are composed of two or more atoms. Even pure oxygen isn't individual atoms; oxygen is the O2 molecule composed of TWO oxygen atoms. Except within the cores of stars, hydrogen, the most common element, normally exists as the H2 hydrogen molecule. So in general, matter is composed of molecules, which are composed of atoms.
Sounds like an element to me.
Yes, an element is composed of millions of identical atoms.
Matter is composed of atoms, which are the basic units of matter. Atoms are made up of protons, neutrons, and electrons. The way these atoms are arranged and interact with each other determines the properties of different types of matter.
All matter
atoms
The ATOMIC THEORY states that all matter is composed of very small particles called atoms, and that those atoms cannot be broken apart.
Yes, all matter is composed of atoms.
These are atoms of an isotope.
That all matters are made up of atoms
It's Atoms
Robert Boyle
Yes, they are called atoms.
