A periodic table is a table of
chemical elements arranged Group 7 are k
in order of atomic number so group 7 the re
that elements with similar point increase
chemical properties appear in Group 2 known as alkaline earth metals
forces.
vertical columns.
Group1- Every element in that column have 1 electron on its outer shell and this group
can be known as alkaline metals this is the reason why all the elements are in group 1.
Groups are the columns going vertical and periods
In group 1 as you go down the elements become more reactive and also as you go
are the rows going horizontal
down the boiling point also decreases.
D block includes Ti,V, Cr, MN,Fe,Co,Ni,Cu,Zn
D Block- includes
SC,Ti,V,Cr,Mn,Fe,Co,Ni,Cu,Zn
S Block-includes K,Ca,Sc
