Question

Claculate the formal charge on atoms in co32- ion and no2-ion

Answer 1

Heya!
--------

-----------------------------------------------------------------------------------------------------

◾What is Formal Charge ?

⭐Formal Charge is the difference between Number of Valence electrons and Number of Bonded electrons .

Fc = V - L - 1/2 S
=================


↪Here V represents Valence electrons .

↪L represents lone pair

↪S represents Shared pair .

--------------------------------------------------------------------------------------------------------

✔Coming to the Question:
----------------------------------------------------

↪Calculate the Formal Charge on :

1. ] NO2 - [ Nitrate Ion ]

=> The structure are given in attachment . The atoms I have numbered to
make it clear .


1). 1st Oxygen

=> 6 - 4 - 1/2 × 4

=> 0

2) . Nitrogen

=> 5-2 -1/2 × 6

=> 0

3). 2nd Oxygen

=> 6-2 - 1/2 × 6

=> 1


-----------------------------------------------------------------------------------------------------



[ 2 ]. CO3 2- [ Carbonate Ion ]

✔Refer to the Attachment for the bonding. The atoms have been numbered .


1). 1st Oxygen :

=> 6 - 4 - 1/2 × 4

=> 0

2). Carbon Atom

=> 4 - 0 - 1/2 × 8

=> 0

3). 2nd Oxygen

=> 6-6 - 1/2 × 2

=> -1

4). 3rd Oxygen

=> 6-6 - 1/2 × 2

=>. -1
