[Kr] 4d7 5s1
The noble gas nearest to Phosphorus (P) is Argon (Ar).
This gas is neon.
No noble gas is isoelectronic with the element chlorine. But argon is isoelectronic with the chloride ion.
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.
No.
Argon (Ar) is the nearest noble gas to potassium.
The noble gas nearest to Phosphorus (P) is Argon (Ar).

This gas is neon.
Yes it is. Argon (atomic number 18) is the noble gas that is nearest to calcium (atomic number 20)
No noble gas is isoelectronic with the element chlorine. But argon is isoelectronic with the chloride ion.
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.
Rubidium is a solid and a metal.
Neon.
Every element that isn't a noble gas, wants to become isoelectronic or have the same number of electrons as its nearest noble gas. This is because noble gases are very stable, while other elements aren't. Forming compounds allows elements to gain or lose electrons, which allows them to become like their nearest noble gas.
Rubidium has an atomic number of 37, making it an alkali metal. This means that its last shell is an s with only one electron. The full notation is [Kr] 5s1.
