Se has to gain two electrons
1 electron
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.
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.
False; it reacts so that they acquire the electron structure of a noble gas.
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.
1 electron
Atoms will gain, lose, or share electrons to match the number of outer shell electrons of a noble gas.

it should gain 3 electrons
Noble gases
Noble gases have a full outer electron shell, making them stable and chemically inert. This arrangement gives them little tendency to gain, lose, or share electrons with other atoms, making them nonreactive under normal conditions.
Ions that are formed when metals gain electrons are called anions. This process allows metals to achieve a stable electron configuration by filling their outermost energy level, similar to noble gases.
nitrogen has 5 valence electrons. It should gain 3 electrons to achieve a noble gas configuration.
All halogen family elements need to gain 1 electron to attain a noble gas configuration. This is because noble gases have a full outer shell of electrons, which is the most stable configuration in terms of electron arrangement.
