Why does the electron transfer process absorb energy?
Why does the electron transfer process absorb energy?
- Due to the exothermic energy component involved in the process
- Due to the conversion of metallic lithium and diatomic fluorine to separate gaseous atoms
- Due to the endothermic steps involved in the process (correct)
- Due to the release of energy when ions come together and form a solid
