What can be inferred from the results of scheme a about the relative thermodynamic stabilities of compounds 4a and 4b?

a. they are equally stable.
b. compound 4a is less stable than compound 4b.
c. compound 4a is more stable than compound 4b.
d. nothing can be inferred about relative thermodynamic stabilities.

there is none because earth is stationary and flat.

um i think it might be a car?

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
