1 electron
Se has to gain two electrons
Chlorine gains 1 electron to achieve the noble gas electron configuration of argon.
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.
No, they are not. Fluorine, chlorine, and iodine are halogens, meaning they have 7 valence shell electrons. They are the second most nonreactive group of elements, besides the noble gases, which have 8 and do not react at all.

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.

Elements on the left side of the periodic table, such as alkali metals, tend to lose electrons to achieve a noble gas configuration.

Atoms will gain, lose, or share electrons to match the number of outer shell electrons of a noble gas.
The noble gas distribution for chlorine (Cl) is 2,8,7. This means it has two electrons in the first energy level, eight electrons in the second energy level, and seven electrons in the third energy level. Chlorine achieves stability by gaining one electron to complete its outer energy level to achieve the same electron configuration as argon, a noble gas.
Chlorine need one extra negatively charged electron to be a noble gas.
No, they are not. Fluorine, chlorine, and iodine are halogens, meaning they have 7 valence shell electrons. They are the second most nonreactive group of elements, besides the noble gases, which have 8 and do not react at all.
Other elements can acquire a noble gas configuration by gaining or losing electrons to achieve a full outer electron shell, similar to that of a noble gas. This can be done through forming chemical bonds with other elements or ions in order to stabilize their electron configuration.
Atoms of Cl must gain one electron to form a noble gas arrangement, as it needs a full outer shell with eight electrons to achieve stability, similar to the nearest noble gas, argon.
Sulfur must to have an electrons octet.
Electronic configurations are the arrangement of electrons in the orbits or shells. The maximum number of electrons that can be accommodated in the shell goes as 2-s, 8-p and so on.. So, when the last shell contains the maximum electrons it can hold, there is no possibility of any reaction to occur because it has the 8 electrons in the final shell already. This arrangement in any atom, which shares or donates or accepts electrons to form the final arrangement as above is called noble gas configuration
