Question

What are the 6 possible identities of an ion with the electron configuration of 1s² 2s² 2p⁶ ?

Answer 1

The 6 possible identities of an ion with the electron configuration 1s² 2s² 2p⁶ are Oxygen ion (O⁻²), Nitride ion (N³⁻), Chloride ion (Cl⁻), Fluoride ion (F⁻), Oxygen atom (O), and Oxide ion (O²⁻).

Step-by-step explanation:

The electron configuration 1s² 2s² 2p⁶ represents the configuration of a neutral oxygen atom. Oxygen can form ions with different charges by gaining or losing electrons. Here are the 6 possible identities of an ion with this electron configuration:

1. Oxygen ion (O⁻²): Gains 2 electrons to achieve a stable, noble gas configuration of 1s²2s²2p⁶.
2. Nitride ion (N³⁻): Gains 3 electrons to achieve a stable, noble gas configuration of 1s²2s²2p⁶3s²3p⁶.
3. Chloride ion (Cl⁻): Gains 1 electron to achieve a stable, noble gas configuration of 1s²2s²2p⁶3s²3p⁶.
4. Fluoride ion (F⁻): Gains 1 electron to achieve a stable, noble gas configuration of 1s²2s²2p⁶.
5. Oxygen atom (O): Remains neutral with its original configuration of 1s²2s²2p⁶.
6. Oxide ion (O²⁻): Gains 2 electrons to achieve a stable, noble gas configuration of 1s²2s²2p⁶3s²3p⁶.
