Each shell consists of one or more subshells (named s, p, d, f and g). The periodic table is a chart of known elements grouped by their atomic number, the number of protons in the nucleus of that element. Therefore, the bottom-left most element (francium) is predicted to have the lowest electronegativity and the top-right most element (fluorine) is predicted to have the highest electronegativity. Elements are arranged from left to right and top to bottom in order of increasing atomic number. Wi… Groups 1, 2, and 13–18 are the main group elements, listed as A in older tables. The elements are stacked in such a way that elements with similar chemical properties form vertical columns, called groups, numbered from 1 to 18 (older periodic tables use a system based on roman numerals). In the modern periodic table, the electronegativity of elements increases across a period (row) and decreases down a group (column). metals are found on the left hand side of the table; The material on this site can not be reproduced, distributed, transmitted, cached or otherwise used, except with prior written permission of Multiply.
