Period 3 Elements – Summary of Physical Properties Advanced Chemistry Book + website The elements in Period 3 of the periodic table are the elements sodium to argon. They represent the most straightforward trend in properties. As the atomic number of the elements increases across a period‚ the trend is from metallic to a non-metallic character. Electronegativity is a measure of an element’s ability to attract a shared electron pair to itself. Metals have a smaller electronegativity than 1

Although this idea may seem simple‚ it is very difficult to decide if a substance is indeed an element or a compound. There were twelve chemical elements discovered in ancient times‚ but it was not known that they were elements. Another 76 elements were discovered between 1557 and 1925. Many mistakes were made in
