The elements of the second second Period of the periodic table are given along li,be,b,c,n,o,f and give reason to explain why atomic radius decreases from like to f and identify the most metallic and nonmetallic elements
Anonymous:
Because in the second period of the periodic table the no. electron shells remain the same but as we move towards right in a period the no. of protons in the nucleus increase gradually therefore they attract the shells with greater force thereby decreasing the atomic radius.
most metallic element is Li(lithium) and most non metallic is F(Fluorine).
Thanks
my pleasure
Hello
What physical and chemical properties of element were used by Mendeleev in creating his periodic table list observation which posed a challenge to Mendeleev's periodic table
reassess ur question bro... i think u've written it wrong ...

because the force of attraction of the nucleus decreases in a period,since their atomic number increases(li to fl)and the most metallic element is Li and nonmetallic element is F though oxygen also considered...
