Group one has seven known elements, the most of any of the 18 groups on the Periodic Table so far.
Elements in the same group are most similar.
the group1 elements
Noble gases (or group 18 elements)
The elements from the group 12 are not the most reactive chemical elements.
Group 1 or alkali metals are the most metallic elements.
D - block contains most elements.... ie,from 3rd group to 12th group
As a general rule, these are the elements toward the top of the group in the periodic table.
In space, the most common elements are?
group 17 elements (halogens)
the most stable element group is the noble gases group
In the periodic table, the elements are grouped according to their properties. Elements in a group has an equal number of valence electrons. So the elements in a group have most common chemical properties.
Group 17, the halogens
