Rubidium Metal Sample ( Dnn87)
The alkali metals are the elements located in group IA of the periodic table (the first column). The key characteristic these elements share in common is that they all have one electron in the outer electron shell. This lone electron is loosely bound, making this a set of reactive metallic […]

Periodic Table Trends 1
The Periodic Table is called this not just because it is a table of the elements, but because it is arranged to reflect the periodic trends of the elements.   This table shows the periodic table trends of six different physical properties of the elements: atomic radius, electron affinity, electronegativity, […]

Periodic Table Metals - 2017 23
Most elements can be considered metals. They are grouped together in the middle to the left-hand side of the periodic table. The metals consist of the alkali metals, alkaline earths, transition metals, lanthanides, and actinides. Properties of Metals The metals share several common properties, including: solid at room temperature (with […]
