Periodic Table Sections

The periodic table also known as the periodic table of elements is a tabular display of the chemical elements which are arranged by atomic number electron configuration and recurring chemical properties the structure of the table shows periodic trends the seven rows of the table called periods generally have metals on the left and nonmetals on the right.
Periodic table sections. The periodic table may look complicated but much of it comes down to one simple pattern. Look up chemical element names symbols atomic masses and other properties visualize trends or even test your elements knowledge by playing a periodic table game. 2 valence electrons form 2 ions reactive though not as much as group i metals very high melting boiling points ions are not soluble in water.
Elements in the center section of the periodic table. The transition from metal to nonmetal elements. Elements in group iia of the periodic table.

The periodic table orders elements by increasing atomic number which is the number of protons in the atom of an element.
