Calculate the δg for the following system. then state if the system is spontaneous or not spontaneous. δh = 147 kj δs = -67.0 j/k t = 149 ãƒâ‚ã‚°c 2.8 x 104 kj; not spontaneous 157 kj; not spontaneous 175 kj; not spontaneous 2.8 x 104 kj; spontaneous 157 kj; spontaneous 175 kj; spontaneous

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.
