Hint :Yes, this is true that the chemical formula given in the question is the error. No such ion with the chemical formula exists NO3 in any chemistry books. It is just a mistake. The ion which exists is nitrate ion.

Complete Step By Step Answer:
The ion given in the question NO3 is a typo. It does not exist in reality. The ion which exists is nitrate ion which has the chemical formula NO3 . Although the chemical formula almost looks the same, we get confused between the two ions. The nitrate ion is a polyatomic ion and the salts which contain this nitrate ion are called nitrates. The nitrate ion is a conjugate base of nitric acid.
The nitrate ion consists of one central atom i.e. nitrogen atom and it is surrounded by three identical bonded oxygen atoms. Its arrangement is trigonal planar. The nitrate ion has a formal charge of 1 . These nitrates also show resonance. It has three resonance structures.

There are many applications of nitrate ions due to their high solubility and biodegradability. It is mainly used as fertilizers in agriculture. Some of the examples of nitrate fertilizer are ammonium, sodium, and magnesium salts etc. It is also used as oxidizing agents in explosives where the oxidation of carbon compounds releases large amounts of gases. Sodium nitrate is used to remove the air bubbles from some ceramics and molten glass.
Hence, no such ion NO3 exists in chemistry.

Note :
Don’t get confused between these two ions NO3 and NO3 anions. NO3 is called a nitrate ion whereas NO3 does not exist. Also, there is a nitride anion N3 , it is the conjugate base of hydrazoic acid HN3 .
