Group 1 metals

Group 1 metals This is a group of highly reactive metals also called the alkali metal series, and contains the metals Lithium, Sodium, Potassium, Rubidium, Cesium and Francium. Hydrogen is also a member of this group however, it shares both the properties of a group 1 metal and a group 7 non-metals. These metals possess…...

Group II metals

Group II metals The electronic configuration of the group 3 elements is shown below: Element Electronic Configuration Be – Beryllium 2,2 Mg – Magnesium 2,8,2 Ca – Calcium 2,8,8,2 Similarly to the group 1 elements, the group II elements react by losing electrons.  This happens in order to achieve the electronic configuration of the closest…...

Group VII

Group VII This group includes the elements fluorine, chlorine, bromine and iodine. They all possess 7 valence electrons (7 electrons in their outer shell). The Electronic configuration is shown below: Element Electronic configuration Fluorine 2,7 Chlorine 2,8,7 Bromine 2,8,8,7 Elements in this series react by gaining a single electron when they react with metal atoms…...
