WebAccording to Dobereiner’s system, there are three types of triads: Similar triads are triads in which the elements are similar in terms of their chemical properties. For example, the triad of hydrogen, oxygen, and nitrogen is similar because all three elements are gases. Ionic triads are triads in which the elements held together by ionic bonds.
