Your answer. . Chemistry The nucleus of an atom is the center portion of the atom that
contains most of its mass. A formula for the radius r of a nucleus of an atom is
r= (1.2 x 10-15)A meters, where A is the mass number of the nucleus. Suppose
the radius of a nucleus is approximately 2.75 x 10-15 meters. Is the atom boron
with a mass number of 11, carbon with a mass number of 12, or nitrogen with a
mass number of 14?

Consider hydrogen in an excited state n = 5n=5 that emits photons to reach the ground state. there are various possible transitions other than straight to the ground state that can occur; for example, it can drop to the n = 3n=3 state followed by the n = 3n=3 to the ground state transition. which of the possible transitions will result in the emission of a photon in the visible region?
