Solution: Triads are a type of arrangement of elements that is commonly found in nature. For example, the elements lithium, sodium, and potassium form a trio. These elements have atomic masses of 6.9, 23.0, and 39.0 g/mol, respectively. Na has an atomic mass of around the same as Li and K, which is about equivalent to each other.
The three elements A, B and C with similar properties have atomic masses X, Y and Z respectively. The mass of Y is approximately equal to the average mass of X and Z. What is such an arrangement of elements called as? Give one example of such a set of elements.
