halogens & noble gases
Block d contains transition metals, which include elements from group 3 to group 12 on the periodic table. These elements have partially filled d orbitals and exhibit similar chemical properties.
All groups in the periodic table contain chemical elements.
s block and especially group 1 elements.
D - block contains most elements.... ie,from 3rd group to 12th group
Gallium is in group 13 of the periodic table. The other elements in this group are Boron, Aluminum, Indium, and Thallium.
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
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.
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.
Main group elements include elements (except hydrogen) in groups 1 and 2 (s-block), and groups 13 to 18 (p-block).
