All the atoms have the same number of protons (element type).
All atoms of any single element have the same number of protons and electrons.
the smallest particle in the element
Atoms exist only on Earth. Atoms are smaller than quarks. (apex)
An atomic number is actually related to an element and not an atom. Therefore, the question is not relevant. It is NOT atoms that have an atomic number; it is the element.
Dalton's theory was based on five principle: 1.An element is fundamentally different from any other element. 2.All atoms of a each element are identical. 3. Atoms from one element can combine with atoms from another element to form compounds. 4. Atoms cannot be created or divided 5. Element are made of small particle called atoms.
The number of protons is identical in all atoms of an element.
protons
An atom is the smallest unit of any element.
Argon is an element and all the atoms in argon are argon atoms.
Because they are all the same type of atoms. Oxygen is an element. If you have 10 oxygen atoms, they will all behave like oxygen, since they are the same element.
All atoms of the same element are not identical. The atoms of same element with different number of neutrons are called as isotopes. Although, the number of protons and electrons are same in every atom.
The atoms of an element are all identical.
