e. The radial function for the 3s orbital in the hydrogen atom is given below:
(27 – 180 + 202)e
(o = )
R3s =
ao = 52.92 pm
Calculate the distance(s) of the node(s) of the 3s orbital of the hydrogen atom from the nucleus.
The nucleus of a certain atom has a radius of 4.0 × 10^-15 m. An electron orbits the nucleus at a radius of 1.5 × 10^-10 m. Imagine the electron orbit is on the surface of a sphere and that the shape of the nucleus is spherical. Approximately how many nuclei would fit into the sphere on which the electron orbits?
An aspiring physicist wants to build a scale model of a hydrogen atom for her science fair project. If the atom is 1.00 m in diameter, how big should she try to make the nucleus?
