Ions and isotopes of elements are not shown in periodic table. Example: If X +2 ion has 10 electrons, find its group and period number. Number of protons=10 + 2=12 For notes and updates to this table, see www.iupac.org. This version is dated 28 November 2016. Copyright © 2016 IUPAC, the International Union of Pure and Applied Chemistry. IUPAC Periodic Table of the Elements The periodic table is a unique tool, enabling scientists to predict the appearance and properties of matter on Earth and in the rest of the Universe. As one of the main sponsors of IYPT2019, Solvay considers this initiative as an excellent opportunity to highlight its strong devotion to chemistry bringing innovative solutions to society and our planet.

Check out new elements: Flerovium (Fl 114) Livermorium (Lv 116) and proposed: Nihonium (Nh 113) Muscovium (Mc 115) Tennessine (Ts 117) Oganesson (Og 118) In the periodic table, the vertical columns are called ‘groups’ and the horizontal rows are called ‘periods’. The modern periodic table is based on the modern periodic law put forward by the English physicist Henry Moseley, which states that “the properties of elements are periodic functions of their atomic numbers”. Periodic trends in the properties of the elements can be observed down the groups and across the periods of the modern periodic table. 35Br: 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 10 4 p5 Since last sub shell is "p" group of Br is A. Elements in group B have electron configuration ns and (n-1)d, total number of electrons in these orbitals gives us group of element.
ii) calculate the number of atom Y assming the mass of element Y similar with 16. 3 g of sulphur.
