well there is 2 ways physical and chemical.
physical it means itll depend on its size
chemical mean itll depend on its atomic weight (protons+neutrons)
Yes, atoms of different elements have a different number of protons.
Isotopes are atoms of the same elements with different number of neutrons.
A compound must have at least two atoms of different elements.
no
Elements are made of atoms. Each element is made up of the same kind of atoms, having the same atomic number.
Elements are identified based on the number of protons in their atoms, which is known as the atomic number. Each element has a unique atomic number, allowing scientists to distinguish between different elements.
Atoms of only some elements. The number of these atoms is extremely great, not millions.
An atom is a general term. Elements are specific kinds of atoms that vary by the number of protons they have.
