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.
the alkali metals have 1 electron in their outer most shell. in order to obtain a full outer shell they have to lose this electron. so when they react with another metal they lose this electron and the outer most shell.
they will lose electron to form mono positive cation
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.
It doesn't lose or gain
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.
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.
The most reactive elements require to lose or gain the least number electron(s) to attain a noble gas structure. These are elements in group one as they need to lose one electron, and elements in group seven as they need to gain one electron.
Something that can happen is they can gain, lose, or share four elements.

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.

The elements in group 7A or 17, gain one electron during ionic bonding, or share one electron when undergoing covalent bonding.

Hydrogen and Chlorine react so that they're atoms can have a full outer shell with eight electrons. Hydrogen just has to lose an electron and Chlorine just has to gain an electron, so they react and make Hydrogen Chloride.
The elements that gain two electrons when they react are the ones found in group 14 of the periodic table. Oxygen is a good example of such elements.
