Argon's an element.
The phosphorus -3 ion. The phosphorus -3 ion gains 3 electrons and acts like argon.
Argon does not normally form ions.
No, it does not.
No, it is a monatomic 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.
Argon's an element.
sulfur has 16 electrons with a neutral charge the most common ion formed is the sulfide ion, with a negative 2 charge to get a negative 2 charge, it gains 2 electrons, thus fulfilling the octet rule and acquiring the electron configuration of argon
The phosphorus -3 ion. The phosphorus -3 ion gains 3 electrons and acts like argon.
Argon does not normally form ions.
Argon
2- Because, to get a full octet, Sulfur gains two electrons to become like Argon, thus it gains a charge of 2-.
[Ne]3s^23p^6P3-. P is in group V (group 15 moden periodic table) so gains three electrons, each carrying a 1- charge.
It doesn't become an argon atom because it (Cl-) still has 17 protons, and an argon atom has to have 18 protons.
Argon
No, it is a monatomic gas.
No, it does not.
