This study, observe scientific research published in chemistry in the international databases and extract the largest database on this science. this database is scoups, where researcher 258806 survey research publication of the 2017:2013 period, in order to identify the Numerical , geographic, linguistic and objective trends to chemistry science , monitor and analyze Authoring trends, geographical and professional affiliations of authors and publishing trends through monitoring top periodicals, top institutions that support research and publishing. the study includes four chapters: Chapter 1: Chemistry and its role in scientific research. Chapter II: General characteristics of published research in chemistry in terms of time allocation to branches of chemistry and qualitative substantive and geographical distribution and linguistic distribution, chapter three: Authoring trends of scientific research published in chemistry in terms of top authors The highest coefficient effect for each author. Chapter IV: Publishing trends in terms of the top leagues in chemistry and institutions that support international publication in chemistry. The Study relied on the bibliographic bibliometric approach which depends on the bibliographic and inventory lists that confine and describing scientific productivity, studying numerical , qualitative and objective trends of this scientific productivity and their evolution with the evolution of time. The study reach a number of results, including: The importance of chemistry science and Entry into different industries and \ importance of studying subject trends of this science and monitoring developments in time, industrial chemistry has achieved the highest for publication as published within the last five years 20856, agro chemistry It has reached 694 search during the last five years by 0.27%, and is also a Radio Chemistry Less fields of research and study with 1563 in search over the last five years by 0.60% of total 258806.
