Now, to make the diagrams simpler we often just draw them as circles. So now an atom is the smallest particle of an element. There are over one hundred different elements and these are all made of ...

But every now and then, a particle bounced back as though it had hit something solid. After tracing many particles and examining the patterns, Rutherford deduced that the atom must have nearly all ...

Particle acceleration using DC voltages ... subatomic particles as listed in the table below. Studying the structure of the atom on smaller scales and being able to produce particles with higher ...
