THE PERIODIC TABLE OF ELEMENTS 27 MATHEMATICAL REQUIREMENTS 28 GLOSSARY OF TERMS USED IN CHEMISTRY PAPERS 29 SPECIAL NOTE 30 . b. To avoid this, the metals are stored under oil, They also react vigorously with water, forming the alkaline hydroxide and releasing hydrogen gas, Because alkali metals are such reactive metals, they combine directly with reactive non-metals such as the halogens to form salts, low melting and boiling points - increases down the group, elements become darker and solidify down the group, because of their atomic size, which increases down the group, therefore it becomes more difficult for the nucleus to attract an electron to form an ion, most reactive is fluorine; least reactive is iodine, all halogens form ions with single negative charge eg F, Any halogen above another in the group will displace it from a solution of its salt ---->, least reactive elements in the gaseous state; do not form bonds, have stable electronic configuration with full electrons on their shells. The Periodic Table: – Shows elements arranged in increasing atomic numbers/ proton numbers – Has vertical columns called groups and horizontal rows called periods.
