Calculate the probability that the electron in the ground state of a hydrogenic atom of nuclear charge Z is measured to be inside the nucleus. A nucleus with A nucleons (Z protons and A-Z neutrons) has an approximate radius of r 11.2 * 10-15 m2A1>3 . Calculate the probabilities for hydrogen and uranium-238.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
