Answer 1

The different elements of the periodic table are:

(Group-1)                              (Group-2)                             (Group-3)

1)H(Hydrogen){1}                  4)Be(Beryllium){9}               21)Sc(Scandium){45}

3)Li(Lithium) {7}                     12)Mg(Magnesium){24}       39)Y(Yttrium){89}

11)Na(Sodium){23}               20)Ca(Calcium){40}           57) La(Lanthanum){139}*

19)K(Potassium){39}              38)Sr(Strontium){88}           89)Ac(Actinium){227}ъ

37)Rb(Rubidium){85.5)          56)Ba(Barium){137}                  

55) Cs(Caesium){133}               88) Ra(Radium){226}

87) Fr(Francium){223}

(Group-4)                            

22)Ti(Titanium){48}              

40)Zr(Zicronium){91}

72) Hf(Hafnium){178.5}

104)Rf(Rutherfordium){261}

                                     E.T.C.

I have forgotten others, see in the picture.

Answer 2

The elements in the Periodic Table are grouped into 10 categories as follows:

*Alkali metals – Lithium to Francum

*Alkaline-earth metals – Beryllium to Radium

*Lanthanides – Lanthanum to Lutetium

*Actinides – Actinium to Lawrencium

*Transition metals

*Post-transition metals – Aluminum, Gallium, Indium, Thallium, Tin, Lead and Bismuth

*Metalloids – Boron, Silicon, Germanium, Arsenic, Antimony, Tellurium and Polonium

*Nonmetals – Hydrogen, Carbon, Nitrogen, Phosphorus, Oxygen, Sulfur and Selenium

*Halogens – Fluorine to Astatine

*Noble Gases
