What is charge shift bonding?

Can someone explain to me charge shift bonding? I recognize that it is proposed as another domain of bonding - one different from ionic and covalent bonding. I am also told that $\ce{C-F}$ exhibits ...

What holds atoms together? [duplicate]

I know atoms are held together by Ionic and Covalent bonds and i understand the ionically bonded atoms are held together by electrostatic forces. What about covalent bonds? How are molecules of bonded ...

How can a neutral atom attract electrons when it's supposed to have zero charge?

A neutral atom is an atom with an equal number of protons and electrons We know the force of attraction between the proton and electron is equal and assuming that: one proton's positive charge ...

Where does the energy of formation of covalent bonds come from?

Consider two $\ce{H}$ atoms. Since the proton in one attracts the electron in another, they attract each other, and form a covalent bond ($\ce{H-H}$). Bond forming requires energy (436 kJ/mol for an $\...

Electron pairing and repulsion [duplicate]

If two electrons that get paired occupy the same orbital, then wouldn't there be a heavy amount of repulsion between the two? As is, since electrostatic force ${\displaystyle \propto }$ $\ce{ 1/ (...

Why does covalent bonding satisfy atoms?

Having to retake an introductory chemistry course has gotten me thinking. Covalent bonding is where electrons are shared between two atoms that both want more electrons. Let us take $\ce{O2}$ as an ...

How are octet-rule models supported by thermodynamics and quantum theory? [closed]

I understand that the four quantum numbers dictate how many electrons can "fit in a shell," but I don't understand how gaining a full octet is particularly energetically favorable. The example of ...

Why does formation of bond releases energy and where does that energy come from? [duplicate]

I am having a hard time to imagine why does bond formation releases energy and where does that energy comes from?? It is easy to understand that breaking a bond requires energy because it can be ...

Why does a bonding molecular orbtial increase stability? [duplicate]

When two atomic orbitals come together, they fuse to form a molecular orbital. There is a large probability that the electrons will spend time between the nuclei. This will reduce the nuclei - nuclei ...

How does binding energy “manifest” itself? [closed]

The concept of binding energy is, that it is equal to the energy that is needed to separate atoms in a covalent bond. I think I have understood that. The electrostatic powers between the atoms create ...

How do bond electrons covers both atoms in covalent bond? [duplicate]

I want to know how bonding electrons behave when they have to cover for both atoms. Electrons can spin around only one atom right? If so, then what happens when a covalent bond forms? Let's say we ...

What are chemical bonds made of, and how do they form? [duplicate]

All atoms are linked together by chemical bonds, but what are the bonds themselves made of? I'm sorry that's a stupid question, but I'm only 14, and haven't entered high school yet, and my science ...

What force attracts electrons from another atom to a non-closed valence shell? [duplicate]

As I understand the balance in an atom is reached when the number of protons is equal the number of electrons. And the force responsible for this is based on each proton attracting one electron. But ...
