Love is like a bond between two chemical elements, everyone is looking for potential partner, that is we search for what we lack of And share what we have. Like for example the bond that exist between sodium and chloride atoms, the bond between them is called ionic bond, where the non-metal atom gives its extra valence electron to the one who lacks it(sodium). Chlorine has one extra valence electron while sodium lacks one , sodium and chlorine attrack to each other that form ionic bond, the reaction produces NaCl or salt and they are held together with elctrostatic force. The secret why these two atoms are strongly bonded with each other is their give and take relationship that exist between them. Chlorine gives and sodium takes. This give and take relationship is what keeps them strongly connected to each other. The aim of reaction is to produce 8 electrons on their outershell so as to make them stable as the nearest noble gas.
There is another type of bond that keeps atoms held together, this is the covelent bond. This can only happen to non metal elements such as carbon and oxygen, notice that these two atoms are disimilar thus they are gonna form polar covelent bond, however this type of bond may also show some property like that of ionic bond because of their electronegativity. The other type of covalent bond is called non-polar covalent bond, this type of bond exist in similar atoms like for example the bond between two similar atom oxygen. In covalent bond electron are shared equally so as to attain the nearest noble gas electron configuration. The main purpose of these bonding is to become stable as the noble gases.
Love is just like these chemical bonds, like ionic bond it involves a give and take relationship to keep each other connected. And like covalent bonds, it involves sharing!.
