How far from the nucleus in angstroms (1 angstrom = 1 10–10 m) is the electron in a hydrogen atom if it has an energy of –8.7210–20 J? The radius of the orbital (r) = n2 a0/Z (n is the quantum number of an orbital, a0 is the Bohr radius with a value of 5.292×10−11 m, Z is the nuclear charge). Hint: figure out n first and the radius of the orbital is the distance.

Imagine that a water molecule is made of two positively charged
hydrogen atoms, each with charge +q, and one negatively charged
oxygen atom, with charge –2q. These atoms are arranged as shown.
The magnitude of the electron charge q = 1.6 x 10^19 C and the
distance unit used in the diagram, “pm”, is picometers, or 10^-12

2) Consider a stellar atmosphere composed of pure helium. You will find the temperature at the middle of the He I partial ionization zone, where half of the He I atoms have been ionized. (Such an atmosphere would be found on a white dwarf of spectral type DB.) The ionization energies of neutral helium and singly ionized helium are Eion-24.6 ev and Eion-54.4 ev, respectively....

Finding the charge to mass (e/m) ratio of the electron Often in physics, we look for ways to find fundamental physical constants. From the set-up demonstrated in class, we are able to find a monumental combination of two physical constants-the charge of an electron (e) and the mass of an electron (m). Since the charge of an electron (e) is well known through other experiments, we will use the ratio of charge to mass to find the mass of an...
