18.1 Periodicity – Chemistry

Nonmetals are shown in green, metalloids in purple, and the transition metals and inner transition metals in blue. Most of the representative metals do not occur naturally in an uncoined state because they readily react with water and oxygen in the air.

PERIODIC TRENDS IN REACTIVITY - University of Kansas

For example, iron reacts with oxygen to form rust (Fe 2 O 3). Some metals are highly reactive and readily oxidize (e.g., the alkali and alka-line earth metals), while others are resistant to oxidation and corrosion (e.g., gold and platinum). As previously discussed

Alkaline earth metal — Wikipedia Republished // WIKI 2

The alkaline earth metals are six chemical elements in group 2 of the periodic table. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). The elements have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure.
