Exam 22: All About Atoms

The effective charge acting on a single valence electron outside a closed shell is about Ne, where N is:

The states being filled from the beginning to end of the lanthanide series of atoms are:

Suppose the energy required to ionize an argon atom is i, the energy to excite it is e, and its thermal energy at room temperature is t. In increasing order, these three energies are:

In a helium-neon laser, the laser light arises from a transition from a _________ state to a _________ state:

For any atom other that hydrogen and helium all electrons in the same shell have:

The most energetic electron in any atom at the end of a period of the periodic table is in:

Photons in a laser beam are produced by:

An electron is in a quantum state for which there are seven allowed values of the z component of the angular momentum.The magnitude of the angular momentum is:

The magnetic field is along the z axis in a Stern-Gerlach experiment. The force it exerts on a magnetic dipole with dipole moment is proportional to:

The group of atoms at the ends of periods of the periodic table are called:

The magnitude of the orbital angular momentum of an electron is what multiple of ? ( is a positive integer.)

The Stern-Gerlach experiment makes use of:

An electron in an atom is in a state with and The angle between and the z axis is:

The group of atoms at the beginning of periods of the periodic table are called:

To observe the Zeeman effect one uses:

A magnetic dipole is placed in a strong uniform magnetic field The associated force exerted on the dipole is:

A laser beam can be sharply focused because it is:

A laser must be pumped to achieve:

No state in an atom can be occupied by more than one electron. This is most closely related to the:

The most energetic electron in any atom at the beginning of a period of the periodic table is in:
