How was Rutherford’s gold foil experiment inconsistent with the plum pudding model of the atom? A.
The model could not explain how alpha particles could be deflected at large angles.
B.
The model could not explain how alpha particles could penetrate the atoms.
C.
The model could not explain why the electrons in the atom would be evenly spaced.
D.
The model could not explain why alpha particles passed through the nucleus without any deflection.

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.
