periodic table. n. 1. (Chemistry) a table of the elements, arranged in order of increasing atomic number, based on the periodic law. Elements having similar chemical properties and electronic structures appear in vertical columns (groups). (ËpÉªÉr iËÉd Éªk, ËpÉªÉr-).
In mathematics, a group is an algebraic structure consisting of a set of elements together with an operation that combines any two elements to form a third element.The operation satisfies four conditions called the group axioms, namely closure, associativity, identity and invertibility.n these groups, for every non-zero element a, all the powers of a are distinct; despite the name cyclic group, the powers of the elements do not cycle. An infinite cyclic group is isomorphic to (Z, +) , the group of integers under addition introduced above.
