Question

Why the radius of an atom cannot be defined precisely???

Answer 1

The radius of an atom cannot be determined precisely due to the following reasons:- 1.There is no sharp boundary of an atom. The probability of finding an electron never becomes exactly zero even at large distances from the nucleus. 2.The electronic probability configuration is affected by neighbouring atoms. For this reason, the size of an atom may change from one compound to another.

Answer 2

Answer:

The radius of an atom cannot be defined precisely because the size of an atom may vary from one combination to another.

Explanation:

The radius of an atom cannot be determined precisely due to the following reasons:-

1. There is no strong border of an atom. The possibility of finding an electron never evolves precisely zero actually at big distances from the nucleus.

2. The electronic probability configuration exists influenced by neighboring atoms.

For this reason, the size of an atom may vary from one combination to another.
