What is the charge of a sulfide ion that is isoelectric with its nearest noble gas?

The charge of a sulfide ion that is isoelectric with its nearest noble gas (argon) is -2. This means that the sulfide ion has gained two electrons in order to have the same electron configuration as the noble gas.


How could iodine atoms react to achieve a noble gas configuration?

Iodine accepts one electron to achieve noble gas configuration. Strontium loses two electrons to achieve noble gas configuration. Nitrogen accepts three electrons to achieve noble gas configuration. Krypton already has a noble gas configuration.


What is the formula of the ion formed when potassium noble gas electron configuration?

The noble gas configuration for potassium is [Ar] 4s^1. To form a cation, potassium would lose its one valence electron, resulting in a 1+ ion. Therefore, the ion formed when potassium achieves a noble gas electron configuration is K^+.


What is the formula of the ion formed when calcium achieves a pseudo-noble-gas configuration?

The pseudo-noble gas configuration for calcium is achieved when it loses two electrons to form a Ca2+ ion. This results in the same electron configuration as argon.
