Period A horizontal row in the periodic table. Strategy: Locate the elements in the periodic table. Members of a group typically have similar properties and electron configurations in their outer shell. Asked for: order by increasing electronegativity and classification. Formulas indicate the type of compounds formed by each group, with R standing for any element and superscripts. The column headings Reihen and Gruppe are German for row and group. Hydrogen is a non-metal, but it is often put in the middle. ![]() Just put a URL to it here and well apply it, in the order you have them, before the CSS in the Pen itself.

You may also use the color-coded periodic table chart with names, symbols. Groups 1, 2, and 1318 are the main group elements, listed as A in older. ![]() 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). Examples: The row starting with hydrogen is 1. The rows are called periods, and they are numbered from 1 to 7. Part 4: Above groups 1, 17, and 18, label the groups reactivity (very reactive.
