Chemical bonds

Postby 205389184 » Sun Oct 27, 2019 6:25 pm

Can somebody explain the difference in formation of ionic compounds and forming a molecule because the notes say that both have to do with achieving the lowest energy.

The formation of ionic compounds involve transferring electrons from a metal to a nonmetal atom, resulting in cations and anions.
Covalent bonds bind nonmetal atoms to form molecules. The ionization energies of these atoms are too high to transfer electrons from one atom to another, so they simply share electrons.

Most elements tend to be in their lowest energy state possible. From what I know...

- Forming an ionic bond would allow the oppositely charged (usually) ions to transfer their electrons to result in lowest energy state.
- Forming a molecule is similar since they try to achieve a lower energy state. However, some atoms are more electronegative than others, so there are times where there would be a partial charge with them (since electrons move so fast).
