Why does nature favor chemical bonding?
Why does nature favor chemical bonding?
- Because it leads to the formation of diatomic molecules
- Because it leads to lower potential energy for individual atoms (correct)
- Because individual atoms are more stable when not bonded
- Because it results in higher potential energy for individual atoms
What is the main reason for the formation of diatomic molecules?
What is the main reason for the formation of diatomic molecules?
- To increase the potential energy of the individual atoms
- To decrease stability of the individual atoms
- Because the molecules formed are less stable than the individual atoms
- Because the molecules formed are more stable than the individual atoms (correct)
What happens as two atoms approach each other to form a covalent bond?
What happens as two atoms approach each other to form a covalent bond?
