The number of protons.
atom and elements are different because one atom makes an element and a element is a pure substance and a atom is a basic particle
atom and elements are different because one atom makes an element and a element is a pure substance and a atom is a basic particle
in an atom protone makes the each element unique
The atoms of each element have a number of protons that is unique to each element. The number of protons makes one atom different from another.
Elements are pure substances that cannot be broken down by chemical means. The atoms of each element have a number of protons that is unique to each element. The number of protons makes one atom different from another.

What is an atom
Elements are inherently homogeneous, because they contain only one kind of atom and therefore can not have different chemical compositions in different parts of a sample of an element.
Dalton predicted that the atom of any element are different from the atoms of all other elements.
atoms Edit: Atoms and elements are two different things, an elements basic form is an atom. The most common elements found in carbon based molecules besides carbon are Oxygen, Hydrogen, and Nitrogen. However, there are others depending on the molecule.
An element is a piece of matter that only contains that one type of atom now an atom is what makes up the element and a compound is a mix of two or more elements that have all of those different types of atom's
An atom is an element. Every atom has a certain amount of protons, neutrons and electrons and these are what define which element that atom is.
