To make it more clear, we can take the example of atoms having atomic number 1 and 18. According to a rule known as something 2-8-8, which means that atoms bonding have to be distributed as 2-8-8 wherein 2 electrons will present in first shell and second and third shell will contain 8-8 electrons respectively.

Oxygen and fluoride are best examples to explain in which both atoms need to make up some electrons to making the atomic shell fill. The first shell of both elements is filled with two electrons, but they need eight electrons for filling second shell. For getting filled, they can either share the required number of electrons or can borrow thus making bond. Sodium needs to lose one electrons while fluoride atom needs to gain extra electron, thus, they together form a bond by losing and gaining electrons and they are known as happy atoms. By giving up one electron, the second shell of sodium will become stable and by gaining one electron the second shell of fluoride will also become stable. They bond together and it is known as electrovalent bond.

For maintaining the stability, sodium and fluoride needs to remain closer to each other by forming a bonded molecule. It can expand and can also depend on atom. Carbon is another example which is well known for its ability to form longer chains by sharing electrons. Water which is known as H2O shares weak bonding and due to this weak bonding they are brilliant controller in energy level.
