(i) The atom contains a central part called nucleus which is surrounded by electrons. (ii) The nucleus of an atom is positively charged. (iii) The size of the nucleus is very small as compared to the atomic size….
Q. What would have happened if the plum pudding model was correct?
If the plum pudding model was correct, all of the alpha particles would have passed straight through the foil with little or no deflection. Alpha particles were known to be much, much more dense than gold.

Q. What if the Thomson model was correct Rutherford would have observed?
If The Thomson Model Of The Atom Had Been Correct, Rutherford Would Have Observed Alpha Particles Going Through The Foil With Little Or No Deflection. Alpha Particles Greatly Deflected By The Metal Foil.
Q. Why did Rutherford use gold foil?
Rutherford used gold for his scattering experiment because gold is the most malleable metal and he wanted the thinnest layer as possible. The gold sheet used was around 1000 atoms thick. Therefore, Rutherford selected a Gold foil in his alpha scatttering experiment….
Q. Did Rutherford use platinum?
Rutherford Uned Platinum For Some Of His Experiments Platinum Is An Excelent Choice To Replace The Gold Foil Because Platinum Has An Atom That Offers Only By One Proton One Neutron, And One Electron OF 4.
Q. What was the outcome of Rutherford’s experiment?
Rutherford’s gold foil experiment showed that the atom is mostly empty space with a tiny, dense, positively-charged nucleus. Based on these results, Rutherford proposed the nuclear model of the atom.
Q. How did Rutherford disprove Thomson?
Ernest Rutherford disproved Thomson’s theory of the atom in 1911 when he showed that atoms are mostly composed of empty space. Rutherford discovered this by firing alpha rays – helium nuclei – at a thin sheet of gold foil.
Q. Why is most matter electrically neutral?
Atoms of matter are electrically neutral because their nuclei contain the same number of protons as there are electrons surrounding the nuclei. Electric current and charged objects involve the separation of some of the negative charge of neutral atoms.
Q. What happens when an atom turns into an ion?
An atom becomes an Ion (a) if it gains one or more electron(s) or (b) if it loses one or more electron(s). When it gains electrons it becomes negatively charged and is called an anion. When it loses electron(s) it becomes positively charged and is called a cation….
