Answer:
D
Explanation:
∆H° = ∆Hf ° (products) – ∆Hf ° (reactants)
I dont know your question but that is true
As you move around there is a change in: electronegativies, ionisation energies, atomic radius etc. different amounts of these properties are going to effect how the element acts
Because H is a non-metal, it has the highest electronegativity. Option (1) H is correct.
Hope this would help~
