I hope you have remembered elements up to 20(Ca) in your previous class. Today I'm going to describe some techniques to remember elements and their atomic masses especially from Scandium (SC) to Zinc (Zn).
Part one
How to remember elements from Scandium (SC) to Zinc (Zn)?
Just say
सचिन, तेन्दुल्कर ,बिराट कोली, क्रिश गेल, मे , फिर, कोही, नयाँ ,सेन्चुरी, जमाएगा
Scandium = Sc = Sachin
Titanium = Ti = Tindulkar
Vanadium = V = Virat Kohli
Chromium = Cr = Chris Gale
Manganese = Mn = Me (मे)
Iron = Fe = Feer
Cobalt = Co = Cohi
Nickel = Ni = Naya
Copper = Cu = Century
Zinc = Zn = Zamayange
Part two
How to memorize atomic mass?
Atomic mass of element up to atomic number 20
i) odd atomic no => (Atomic no)x2 +1
ii) even atomic no => (Atomic no)x2
iii) Exception => H, Be, N, Cl and Ar
Part Three
Atomic mass = (Atomic number)x2 +x
Where x = Three वटा 45 three 55
ie, x = 3, 4,5,4,5,4,5, 3,5,5
Very easy trick😊👍️👏
