The seven diatomic elements are: All of these elements are nonmetals, since the halogens are a special type of nonmetallic element. When trying to define rigorously whether an arrangement of atoms is sufficiently stable to be considered a molecule, IUPAC suggests that it "must correspond to a depression on the that is deep enough to confine at least one vibrational state".
A compound is formed when atoms or Atomi elementi molecole of different elements combine. A compound is a substance that is composed from two or more different elements. This definition does not depend on the nature of the interaction between the atoms, but only on the strength of the interaction. A compound's is a very simple type of chemical formula. negated : perp, wind: ray.
Condensation — the substance changes from a gas to a liquid. Soft MS of carbon dioxide, CO 2. Once your child has got this, they'll find this topic much easier. For example, water is always composed of a 2:1 ratio of to atoms, and ethyl alcohol is always composed of, and in a 2:6:1 ratio.

Elementary substances are made of a single element one type of atoms.
If you change the number of protons an atom has, you change the type of element it is.
