Is this correct?

When an atom goes from excited to ground it releases energy thus is positive.

Atom goes from ground to excited state absorbs energy and is negative.

This is what I got from Kaplan but I feel like releases should be neg and absorption should be positive.

Also,

Bond formation energy... bonds formed are neg and bonds broken are positive?
 
Energy i thought is negative when it is being released and positive when being abosorbed?

A chemical reaction releasing energy is Exothermic and (-)
A chemical reaction absorbing energy is Endothermic and (+)

So the chemical reactions have to deal with atoms being excited so thats what i think... Correct me if im wrong.. any1

I think you are confused to thermodynamic and Periodicitty of the Atomic. the energy of the excited state of the atom is near zero; but, the energy at the ground state is -1312 Kj/mol. So make it simple, excited state energy - ground state energy = positive. that is 1312kj is released when electron comes from the great distance. hope this help. or you can look into the any text.
