In his gold foil experiment, rutherford shot alpha particles at very thin gold foil. what were the results of this experiment? most of the alpha particles bounced back from the gold foil to the observers. all of the alpha particles passed right through the gold foil. most of the alpha particles passed through the gold foil without deflection, except for a small percentage. the alpha particles became attracted to the electrons and got stuck in the gold foil.

Most of the alpha particles passed through the gold foil without deflection, except for a small percentage.

Explanation:

Most of the alpha particles passed through the gold foil without deflection, except for a small percentage.

Explanation:

 The Rutherford experiment throw some interesting results where the most particles passed the gold foil like they where in vacuum, but others particles dispersed with large angle even thought some of them bounce back.

 Rutherfor explain tis behavior assuming that the positive charge in an atom its concentrate in a region called nucleus, where this nucleus its very small compared with the size of the atom.

 The alpha particles used in the experiment where identified as a helium nucleus particles.

where are the vectors ?

no. dot product   =0 when vecs at right angles
