Group 2A elements and their symbols

2년 전

Hy!

Steemit friends!

I am going to describe Group 2A elements and their symbols in periodic table.

Group 2A elements are in left corner of periodic table .All the elements have two electrons in their valance shell.So they have tendency to lose these electrons to form +2 charge ion.The group 2 A elements are also called alkaline earth metals.

Their name and symbols are as:

  • Beryllium        Be
  • Magnesium     Mg
  • Calcium            Ca
  • Strontium         Sr
  • Barrium            Ba
  • Radium             Ra

Thanks....
