if a neucleus were as big as a grape, how would be an atom big?
An alpha particle (the nucleus of a helium atom formed by 2 protons and 2 neutrons with charge q = +2(1.6 x 10-19 C ) is moving perpendicular to a magnetic field of 0.790 tesla at a velocity of 4.60E+6 m/s ; calculate the magnitude of the magnetic force exerted on it.
In the Bohr theory of the hydrogen atom, an electron moves in a circular orbit about a proton where the radius is 0.51 X 10^-10m. Find the electrostatic force between the electron and proton and the electrons speed.
A hydrogen atom is in the 4p state.To what state or states can it go by radiating a photon in an allowed transition?
The hydrogen atom consists of an electron orbiting an effectively stationary proton. Assuming the electron is moving with uniform circular motion and that the radius of the hydrogen atom is 5.49 10-11 m, estimate the speed of the orbiting electron (in m/s) using Newtonian physics.
For a hydrogen atom in its ground state, use the Bohr model to compute each of the following.
How does what you observed relate to the atom-atom bond energies for the different types of atoms?
