Explanation:
Group 2A of the Periodic table contains the Alkaline Earth matals. Those elements are: Beryllium ( Be ), Magnesium ( Mg ), Calcium ( Ca ), Strontium ( Sr ), Barium ( Ba ) and Radium ( Ra ). Beryllium is the lightest member of the group 2A. Ionic radius increases moving down the group ans decreases from left to right across the period of elements. In the group 2A ionic radius increases from Beryllium ( 59 pm - picometers ) to Radium ( 163 pm ). Answer: Beryllium<span> has the lowers ionic radius. </span>
Answer:
When two or more atoms chemically bond together, they form a molecule. Sometimes the atoms are all from the same element. For example, when three oxygen atoms bond together, they form a molecule of ozone (O3). If a molecule forms from atoms of two or more different elements, we call it a compound.
