An extension of K by Q is a group E with the properties that. K is (isomorphic to) a normal subgroup of E, and. E / K is (isomorphic to) Q. If you fix K and Q, there could be more than one … The periodic table is arranged to recognise that certain chemical and physical properties of the elements recur – this is called the Periodic Law. Once the end of a period is reached, the elements continue in the next period below, such that they end up underneath an element with similar properties.
