These Short Tricks (Mnemonics) on Trick to Learn Formal Charge are very helpful for various Medical Entrance Exam like NEET, AIIMS, JIPMER, PGIMER, CBSE Board, ICSE Board, Class 12th, 11th. Here are some mnemonic of this chapter topics listed below. These are very helpful for class 11th and 12th students :-
Trick to Learn Formal Charge
Number of valance electrons – (No. of unshared electrons + No. of bonds)
Example –
NH4+
Formal Charge of N = 5 – (0+4) = +1
Formal Charge of H = 1 – (0+1 ) = 0
So, Formal Charge of NH4+ = 0+1 = +1
(CO3)-2
Formal Charge of O(a) = 6 – (6+1) = -1
Formal Charge of O(b) = 6 – (6+1) = -1
Formal Charge of O(c) = 6 – (4+2) = 0
So, Formal Charge of (CO3)-2 = -2
