Chemical bonds create lower energy?

Postby Mariane Sanchez 1E » Thu Nov 02, 2017 9:42 pm

Hey all,

Why is it that there is less energy when atoms are bonded as compared to when they were separated?

I think it's because when atoms bond, energy is released, so in general when bonded they have less energy than when separate.

To add to the above response, atoms that are bonded are more stable and therefore have less energy than the free atoms which are more unstable.

To add to the previous statement (which also added to its previous statement), atoms bond to achieve noble gas configuration, which is considered low-energy and stable.

When atoms are alone, they tend to be reactive to create that noble gas configuration (octet rule) which is why bonding makes atoms have lower energy overall. Also why noble gases are less reactive, they have the octet and want to stay that way.
