Gains two electrons. S 2-.
The symbol is S2- because to become an ion a sulfur atom gains two electrons and each electron has a 1- charge.
The most common ion formed from a single sulfur atom is a sulfide ion, with a charge of -2.
The sulfur atom only has 6 electrons in its outer shell, and following the octet rule, it wants to get to the closest noble gas. The elements want to have a full outer level, so it will gain 2 electrons to get to 8. So the Sulfur atom now becomes a Sulfide ion.
What has a larger radii, a sulfur atom or sulfied ion and why
The neutral atom is bigger. The ion would be smaller because in order for magnesium to become a positively charged ion, it has to give up its valence electrons, which results in the removal of the outermost energy level. So instead of having three energy levels, the ion now has only two.
ion
The symbol is S2- because to become an ion a sulfur atom gains two electrons and each electron has a 1- charge.
It becomes this ion after the gain of two electrons.
It becomes this ion after the gain of two electrons.
A sulfur atom gains 2 electrons when it becomes a sulfide ion.
A sulfur atom is larger than an oxygen atom.
The most common ion formed from a single sulfur atom is a sulfide ion, with a charge of -2.
The sulfur atom only has 6 electrons in its outer shell, and following the octet rule, it wants to get to the closest noble gas. The elements want to have a full outer level, so it will gain 2 electrons to get to 8. So the Sulfur atom now becomes a Sulfide ion.
A sulfide ion is an ion of just the sulfur atom on its own, whereas a sulfate ion is an ion that is composed of sulfur and oxygen, typically SO42-.
It becomes a sulfur ion with a charge of -2.
What has a larger radii, a sulfur atom or sulfied ion and why
Magnesium is the cation and sulfur is the anion.
