The Irving–Williams series refers to the relative stabilities of complexes formed by transition metals. In 1953 Harry Irving and Robert Williams observed that the stability of complexes formed by divalent first-row transition metal ions generally increase across the period to a maximum stability at copper: Mn(II) < Fe(II) < Co(II) < Ni(II) < Cu(II) > Zn(II).
In the Indian education system of some Indian states, the Pre-University Course (PUC) or Pre-Degree Course (PDC) is referred to as intermediate or +2 course, which is a two-year senior secondary education course that succeeds the tenth grade (known as SSLC or SSC in such states, equivalent to sophomore in the US system) and precedes to the completion of a Senior Secondary Course.

William Albert Noyes (November 6, 1857 – October 24, 1941) was an American analytical and organic chemist.He made pioneering determinations of atomic weights, chaired the chemistry department at the University of Illinois Urbana–Champaign from 1907 to 1926, was the founder and editor of several important chemical journals, and received the American Chemical Society's highest award, the ...
In 1815 [1] and 1816, [2] the English chemist William Prout published two papers in which he observed that the atomic weights that had been measured for the elements known at that time appeared to be whole multiples of the atomic weight of hydrogen.
