The Halogen family (which consists of Fluorine, Chlorine, Bromine, Iodine and Astatine) have 7 valance electrons. I know that the atoms of these elements only need to GAIN 1 electron to fill their outtermost energy level.
Helium is a noble gas with a full outer electron shell, making it stable and unreactive. Its electron configuration is already stable, so it has little tendency to gain, lose, or share electrons with other elements to form chemical bonds. This inertness is why helium does not readily react with other elements.
Hydrogen, lithium, and sodium are classified as reactive elements due to their tendency to easily lose or gain electrons, which leads to the formation of chemical bonds. Hydrogen has one electron in its outer shell and seeks to either lose it or gain another to achieve stability. Similarly, lithium and sodium each have one electron in their outermost shell, making them highly reactive, especially with nonmetals, as they readily lose this electron to form positive ions. Their reactivity increases down the group in the periodic table, making them more prone to react with other elements.
Group 2A elements tend to GAIN electrons!!
Noble gases have a full outer electron shell, making them stable and less likely to form chemical bonds with other elements. Their electron configuration gives them a low tendency to gain or lose electrons, making them unreactive. This inertness is due to the high ionization energy required to remove or gain additional electrons from noble gases.
i guess you mean that the group 1 elements usually lose a electron in order to become stable because the outermost of the group 1 elements have only one valence electron and it is easy to lose one than to gain seven.
Because it's "easier" for the elements to gain or loose just one electron, so they react more readily.
Xenon is a noble gas and typically does not react with other elements to gain, lose, or share electrons in chemical reactions. Its outer electron shell is already full, making it stable and unreactive.
Group 0 elements, also known as noble gases, have a full outer electron shell which makes them very stable. They do not react because they have no tendency to gain, lose, or share electrons to achieve a stable electron configuration.
Elements form ions by either gaining or losing valence electrons. The elements that lose electron(s) and gain electron(s) acquire a positive charge and negative charge respectively. The elements that lose and gain the least electrons require less ionization energy, and are more reactive than elements that need to lose or gain more electrons. For instance, elements in group 1 of the Periodic Table need to lose one electron, and are more reactive than elements in group 2 that need to lose 2 electrons.
Nonmetals tend to gain electrons when they react, rather than lose them. This is because they have fewer electrons in their outer shell and they have a higher tendency to gain electrons to achieve a stable electron configuration.
Two elements will form a compound when they react chemically to bond together and create a new substance with different properties from the original elements. This usually occurs when the elements have a tendency to gain, lose, or share electrons to achieve a more stable electron configuration.
Something that can happen is they can gain, lose, or share four elements.

Argon is least likely to react with other elements because it is a noble gas with a full outer electron shell, making it stable and unreactive. Its electron configuration is already at its most stable state, so it does not need to gain, lose, or share electrons with other elements to achieve stability.
Elements form ions by either gaining or losing valence electrons. The elements that lose electron(s) and gain electron(s) acquire a positive charge and negative charge respectively. The elements that lose and gain the least electrons require less ionization energy, and are more reactive than elements that need to lose or gain more electrons. For instance, elements in group 1 of the Periodic Table need to lose one electron, and are more reactive than elements in group 2 that need to lose 2 electrons.
Basically when elements react they either gain or lose electrons until their outer shell has eight (apart from helium and hydrogen). When elements react and gain or lose electrons they become ions as the number of protons is no longer proportional to that of electrons. elements with a large or low amount of electrons (1 or 7) on their outer shell react easily E.g the alkali metals (group 1 of the periodic table) have only one electron and so must be preserved in oil or they will react with even the air in the atmosphere.
