(metals, non-metals, metalloids, four, seven, s-block, p-block, d-block, f-block).
On the basis of electronic configuration, elements in the modern periodic table are classified Into ______ blocks. Groups 1 and 2 elements are included in ______ and all these elements are metals. (except Hydrogen). Group 13 to 18 elements are included in ______. This block contains metals, non-metals and metalloids. Group 3 to 12 elements are included in ______ and all the elements are ______ elements shown at the bottom of the periodic table i.e. Lanthanides and Actinides constitute ______ and all these elements are metals.
Solution
On the basis of electronic configuration, elements in the modern periodic table are classified Into four blocks. Groups 1 and 2 elements are included in s-block and all these elements are metals. (except Hydrogen). Group 13 to 18 elements are included in p-block. This block contains metals, non-metals and metalloids. Group 3 to 12 elements are included in d-block and all the elements are metals elements shown at the bottom of the periodic table i.e. Lanthanides and Actinides constitute f-block and all these elements are metals.
