halogens & noble gases
Main group element
All groups in the periodic table contain chemical elements.
s block and especially group 1 elements.
group 3 to group 12 elements
Group III-B or 4th, it includes 4 elements of 'd' block and all the 28 elements of 'f' block.
vanadium is in the block of transition elements
The main group elements have fixed valencies but members of the d block have multiple valencies.
Elements in group no.(verticle) 1&2
Group 7 elements are examples of transition metals (or d-block elements)
Group 4 elements on the periodic table contain no period 2 elements whatsoever.
Transition Metals group 3 to group 12 elements
Omitting the f-block elements, there are 18 groups in the periodic table. Groups 1 and 2 contain s-block elements. Groups 3-12 contain d-block elements and groups 13-18 are made out of p-block elements. The only exception is helium is named under group 18, being a noble gas.
D - block contains most elements.... ie,from 3rd group to 12th group
