Neon atom requires energy to remove one electron from its outermost orbit, so also to add one electron into the outermost orbit. Which of the following is correct about fluorine? I. Fluorine releases energy when an electron is removed.
II. Fluorine requires energy to add one electron.

The high oxidising power of fluorine is due to its

Following method of extracting Zn is based on thermodynamics
A: \(2\text{ZnS} + 3\text{O}_2 \rightarrow 2\text{ZnO} + 2\text{SO}_2\)
B: \(\text{ZnO} + \text{C} \rightarrow \text{Zn} + \text{CO}\)
If \(\Delta G_f^{\circ}\) (standard free energies of formation, in kJ mol\(^{-1}\)) of ZnS = -205.4, ZnO = -318.0, SO\(_2\) = -300.4, and CO = -137.3. Free energy changes of the above reaction A and B (respectively) will be:
