## Electron near nucleus

1. The problem statement, all variables and given/known data
1) What is the magnitude of the electric field at a distance of 3.30 ×10−10 m from a thorium nucleus?
2)What is the magnitude of the force on an electron at that distance?
3)Treating the electron classically, that is, as a point object that can move around the nucleus at reasonably slow speeds, what is the period of the electron's motion?
Again treating the electron classically, how fast it it moving?

2. Relevant equations
$$E=\frac{Kq}{r^2}$$
$$F=\frac{K q_{1} q_{2}}{r^2}$$

3. The attempt at a solution
I can't find anywhere of what the charge of the thorium nucleus is.

not even in peridic table or google?
