Why were the results of the gold foil experiment so surprising?* because based on Thomson's plum pudding model, the alpha particles should have
deflected off of the nuclei and bounced back towards the particle accelerator
because the alpha particles should have passed through the gold foil with large
angles based on Thomson's plum pudding model
because based on Thomson's plum pudding model, the alpha particles should not
have traveled to the gold foil
because the alpha particles should have passed through the gold foil with small
angles based on Thomson's plum pudding model

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.

the right answer is c i just did the question.

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.
