Here's why:
* Valence electrons are the electrons in the outermost energy level of an atom. These electrons are the ones that experience the least attraction to the nucleus and are therefore most likely to interact with other atoms.
* Chemical bonding occurs when atoms share or transfer valence electrons to achieve a stable electron configuration, typically with a full outer shell.
There are two main types of chemical bonds:
* Covalent bonds form when atoms share valence electrons. This sharing creates a stable electron configuration for both atoms involved.
* Ionic bonds form when one atom transfers one or more valence electrons to another atom. This transfer results in the formation of ions (atoms with a positive or negative charge) that are attracted to each other.
In both types of bonds, it's the valence electrons that play the crucial role in holding atoms together.
