Love familiar with each of us, but we are at a loss of love. In the history of mankind, the concept of love has been an enigma.
According to legend, Qing Dynasty Cai Hengzi recorded a story in "insects Manlu" , it sounds disgusting, but true thing. Said that a servant of a wealthy family in Hunan resigned, and asked the reason, saying that there was an errand couldn’t be done anymore. Ask what errand? Said that every night an old lady led him to go into an inner room, in a curtain shielding the bed and a woman's lower body stretched out the curtain. The old lady asked him to have sexual intercourse with the woman's lower body, and afterwards the reward to be quite good. Had worked for several days and never seen the woman's face, the poor servant could not endured and finally resigned.
Although this is a history scandal, it hides mysteries of love. Yet, no one explained why. Writer Zhong Acheng simply explained: "This servant like to eat "the cooked", not those "off the lights are all ok," he does not work for the "raw food", even more reward." Then, what magic power is lurked behind the curtain?
Historically, science has been unable to help love and matters of the love were matters only for the arts— literature, song, poetry, painting, sculpture and dance which have engaged in the expansion of the romantic comedy and the description of cruel tragedy.
Chemistry, biology, psychology, philosophy just discussed isolated disciplines of love. But love is an interdisciplinary science across all these areas. Associating the interdisciplinary science with love, laying bare the love's deepest secrets, is this article's aim.
Ionocovalent Theory derived from the microscopic deduction of experiments and mathematics and correlated to the macroscopic induction of the universal observations [2,3]. Accordance with the ionicovalency: the things exist in ionocovalent potential. The ionocovalent potential (IC) is the harmony (/) of ionic kinetic energy (Z *) and covalent environment (r):
IC = Z* / r
Potential: a potential IC, the attraction due to its kinetic energy Z* at a particular position r in environment;
Ionic: kinetic energy Z* (ionizing energy, polarizing energy or activation energy), a subconscious instinct;
Covalency: the distance r that things shared with the environment. So,
Ionocovalency (potential IC) = Ionic kinetic Z * / Covalent environment r
According to the "Ioncovalent Psychology" we concluded that  unconscious, instinct as well as id, incentives, ego and genes are of the ionic function and conscious, experience, socialization, superego and environment are of the covalent function. And the energy, of that Freud looked at people as a closed system of psychic energy that is floating between the conscious and the unconscious part of the human spirit, is the IC-potential:
I (unconscious, instinct, id, ego and genes) C (conscious, experience, socialization, superego and environment) = I (Iz) C (n*rc-1) = E*/ r
Thus, the hormone induced biological sex is unconscious or subconscious sexual instinct, the love aroused by psychological environment is conscious, therefore the emotional love is ionocovalent potential harmony.
We define: Love is a harmony of the sexual instinct with psychological environment:
Love = sexual instinct / psychological environment
Interestingly, "love" in Chinese, its ionocovalency meaning is clearly. "Love" in Chinese is expressed as “爱情”, two letters meaning respectively "sex", "affection".
So in ionocovalency,
爱情 = 爱 / 情,
Love = Sex / Affection
Sexual instinct is ionic, psychological environment is covalent. In chemistry, ionic is ominidirectional and has delocalized bonding and covalent is localized and has the localized covalent bonding .
No affection of love is the sexual instinct which is just an immediately chemical reaction in the physiological flesh and not the harmony with the spirit of affection. Males are just driven by ionic kinetic of hormone to release its potential, and females, on the other hand, are just biologically concerned with safety, and being provided for so their babies will be safe. So men are perfectly capable of engaging in sex without taking into account the affection bonds. That's why prostitutes have always existed.
Therefore, the sexual instinct is not the love. For quite a lot of people love is just a never meet abstraction. The sexual instinct conducts more attractiveness of the opposite sex, love, however, stressed environment relation between the heterosexuals. Seen from the above model, the stronger the attraction (z*) and the closer the environment relation (r), the deeper the love, and vice versa. However, in science, an ideal harmonious distance exists, this is the famous Bohr radius. For a considerable number of people, love has reached a state of harmony, like the electron dances within the Bohr radius of the hydrogen atom .
In "Insects Manlu"，that the servant only vented the love of the ionic hormonal energy without covalent harmonious emotion is not the love. Servant violated ionocovalency theory: "Things are existed in the ionocovalent potential." In order to maintain a balanced energy of system, kinetic energy consumption must be covalently compensated by the potential energy. The hormonal energy consumption of servant that can not be compensated by potential energy from getting emotional harmony with the woman (lower body stretched out the curtain) collapsed. It turned out that the magic power hidden in the curtain is ionocovalent potential.
