Atomic Models
Rutherford's Atomic Model:
This model is also called nuclear model of atom or planetary model or solar model of atom.
Draw backs :
It should take spiral path, come closer to the nucleus and atom should be collapsed. But this is not happening.

The density of the nucleus is of the order of 1015 gcm-3 or 109 tonnes cm-3 or 1012kg/cc. If nucleus is spherical then,
\tt Density = \frac{mass\ of\ the\ nucleus}{volume\ of\ the\ nucleus}=\frac{mass \ number}{6.023 \times 10^{23}\times \frac{4}{3}\pi r^{3}}
