Assertion (A): An ion is more stable than an atom.
Reason (R): An ion is a charged particle.
Assertion (A): An ion is more stable than an atom.
Reason (R): An ion is a charged particle.
The correct option is B Both A and R are true, but R is not the correct explanation of A.
The explanation for the Correct option B):
- Assertion statement:
- With the exception of noble gases, most elements' atoms do not exist in a free state due to the arrangement of their electrons. It is unstable if an atom's outermost shell does not complete an octet.
- In order to reach the electrical configuration of the nearest inert gas, atoms will tend to gain or lose electrons. As a result, atoms only exist in two forms: molecules and ions.
- When atoms gain or lose electrons to achieve the electronic configuration of the nearest inert gas, ions are created. As a result, ions have higher stability than atoms.
- Eg-Sodium (Na) has an electronic configuration: 2,8,1. It becomes ion after losing one electron and gains stability by achieving the completely filled valence shell.
2. Reason statement:
- A charged atom or molecule is known as an ion. It is charged because the number of electrons in the atom or molecule does not equal the number of protons.
- Depending on whether the number of electrons in an atom is greater or less than the number of protons in the atom, an atom can acquire a positive or negative charge.
3. Hence, Both A and R are true, but R is not the correct explanation of A.
The explanation for the incorrect option:
A) An ion is more stable than an atom because ions achieve a stable and completely filled electronic configuration and not because an ion is a charged particle. Thus, Both A and R are true, but R is not the correct explanation of A.
C) A is true but R is also true as ions are charged particles.
D) A is true as ions are more stable than an atom.
The correct option is B)- Both A and R are true, but R is not the correct explanation of A.
