Hello dosto their is one trick to remember the all radioactive series
TNUA -- TERA NAA ULLU AA
T - THORIUM SERIES-4n
N- NEPTUNIUM SERi -4n+1
U- Uranium RADIUM-4n+2
A -Actinium series- 4n+3
Dosto ye trick mene khud bnae hai ,,I hope this will help u

One more trick for u friends
The liquid drop model- the binding energy depends upon general properties
B=B1+B2+B3+B4+B5
A = mass number
B1--- Volume energy
B2-- surface energy
B3-- Coulomb energy
B4-- Asymmetry energy
B5 -- odd even effect
Sari binding energies mass number par depend karti hai
VSCAO --- VISHAL SIR CA OFFICER 😅
Volume --- A
Surface energy --- A⅔
Coulomb Energy ---- A -⁴/³
Asymmetry --- 1/A
Odd even effect--- ( 0, constant / A¾)
I hope this will help u in exam ,, agar trick achi lage ,, plz send me thumb ,, it will motivate me to help u more
