1 electron
Se has to gain two electrons
Chlorine need one extra negatively charged electron to be a noble gas.
Chlorine gains 1 electron to achieve the noble gas electron configuration of argon.
Atoms can achieve a stable outer electron arrangement by gaining, losing or sharing valence electrons with other atoms or ions.
Other elements can acquire a noble gas configuration by either gaining or losing electrons. Elements on the left side of the periodic table, such as alkali metals, tend to lose electrons to achieve a noble gas configuration. Elements on the right side of the periodic table, such as halogens, tend to gain electrons to achieve a noble gas configuration. Elements in the middle of the periodic table may gain or lose electrons to acquire a noble gas configuration, depending on the specific element and its properties.

Chlorine need one extra negatively charged electron to be a noble gas.
The noble gas that has the same electron configuration as a chloride ion is Aragon.
Chlorine gains 1 electron to achieve the noble gas electron configuration of argon.
Atoms can achieve a stable outer electron arrangement by gaining, losing or sharing valence electrons with other atoms or ions.
Noble Gas
Other elements can acquire a noble gas configuration by either gaining or losing electrons. Elements on the left side of the periodic table, such as alkali metals, tend to lose electrons to achieve a noble gas configuration. Elements on the right side of the periodic table, such as halogens, tend to gain electrons to achieve a noble gas configuration. Elements in the middle of the periodic table may gain or lose electrons to acquire a noble gas configuration, depending on the specific element and its properties.
They either gain electrons or lose electrons (which ever one that requires the least)
Atoms will gain, lose, or share electrons to match the number of outer shell electrons of a noble gas.
Chlorine is a non metal and it reacts by gaining electrons rather than losing inorder to attain a stable electron configuration of the noble gases.
needed to give it to a noble gas arrangement
Sulfur must to have an electrons octet.
