Hello friends In the previous post we had known about the history and property of the periodic table and in today's post we will read about the different parts of the modern periodic table. So let's start
Different parts of modern long from periodic table
All elements which are taken in four parts
Sense ------- (1) Left Portion
(2) Right Portion
(3) Middle Portion
(4) Bellow Portion
(1) Left Portion
It consist = Two group
⇒ Two group are - iA, ⅱA = Soft metal
(2) Right Portion
It consist - six group
ⅲA, ⅳA, ⅴA, ⅵA, ⅶA = These are normal elements
ⅷA = Zero group elements or inert gas element.
(3) Middle Portion
It consist - Eight group
ⅲB, ⅳB, ⅴB, ⅵB, ⅶB, and ⅷB, iB & ⅱB = Known as Transition elements
Points -
No of Series - Four Series
Name of Series -
(a) Scandium Series
(b) Yttrium Series
(c) Lanthanum Series
(d) Actinium Series
Total elements = 10
Starting from = Y (Yttrium) Atomic Number: 39.
Ending = Cd (Cadmium) Atomic Number: 48.
(a) Scandium Series
Total elements = 10
Starting from = Sc. (Scandium) Atomic Number, 21
End = Zn (Zinc ) atomic number 30
(b) Yttrium Series
Starting from = Y (Yttrium) Atomic Number: 39.
Ending = Cd (Cadmium) Atomic Number: 48.
(c) Lanthanum Series
Total elements = 10
Starting from = La (Lanthanum) Atomic Number 57
Ending = Hg ( Mercury ) Atomic Number 80
(d) Actinium Series
Total elements = Incomplete -1
Starting from = Ac ( Actinium ) Atomic Number 89
Ending = No
(4) Bellow Portion
It is consist = Two series
Name of two series -
(a) Lanthanide Series
(b) Actinide Series
(a) Lanthanide Series
Known as = 4f series
Total elements = 14
Starting from = Ce ( Cerium ) Atomic Number 58.
End = Lu ( Lutetium ) Atomic Number 71
(b) Lanthanide Series
Known as - 5f series
Total elements = 14
Starting from = Th ( Thorium ) Atomic Number 90.
End = Lr ( Lawrencium ) Atomic Number 103
This Periodic table does note include the inner transition element in the main body
Inspite of the short coming modern periodic table is very clear and expectable
