alpha particles
[3] According to Dalton's model, the atom is a solid sphere. What would the alpha particles do when they hit the
gold foil if Dalton were correct?
[4] According to Thomson, the atom is a positively charged cloud with electrons scattered throughout. What
would the alpha particles do when they hit the foil if Thomson were correct?
What would the alpha particles do when they hit the foil if Thomson were correct

i just learnt this recently but i need to look through my notes again

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.

answer: gold foil experiment - he shot alpha particles at a gold foil
