Chapter 40: Q2Q (page 1246)

An electron in an atom of gold is in a state with n = 4. Which of these values of are possible for it:-3, 0, 2, 3, 4, 5?

Short Answer

Expert verified

The possible values of l with are 0, 2 and 3.

Step by step solution

01

The given data

The given quantum state of the electron, n = 4

02

Understanding the concept of the electronic configuration

The number of possible l states of an atomic orbital for a given quantum number n range from 0 to n-1 positive integer values. Here, l represents the azimuthally quantum state of an electronic configuration.

03

Calculation of all possible values of l

Using the concept, we can say that the number of possible states of l for n = 4 is from 0 to (n - 1) integer values. They are 0, 1, 2, and 3.

Hence, the possible values according to the question are 0, 2, and 3.

A high-powered laser beam λ=600nmwith a beam diameter of 12 cm is aimed at the Moon, 3.8×105kmdistant. The beam spreads only because of diffraction. The angular location of the edge of the central diffraction disk (see Eq. 36-12) is given bysinθ=1.22λd , where dis the diameter of the beam aperture. What is the diameter of the central diffraction disk on the Moon’s surface?

Figure 40-21 shows partial energy-level diagrams for the helium and neon atoms that are involved in the operation of a helium–neon laser. It is said that a helium atom in stateE3 can collide with a neon atom in its ground state and raise the neon atom to state E2. The energy of helium state E3(20.61eV)is close to, but not exactly equal to, the energy of neon state role="math" localid="1661494292758" E2(20.66eV). How can the energy transfer take place if these energies are not exactly equal?

An electron in a mercury atom is in the 3dsub-shell. Which of the following mlvalues are possible for it: -3, -1, 0, 1, and 2?

Consider the elements selenium Z = 34 , bromine Z = 35 , and krypton Z = 36 . In their part of the periodic table, the sub- shells of the electronic states are filled in the sequence 1s2s2p3s3p3d2s2p........ . What are (a) the highest occupied subshell for selenium and (b) the number of electrons in it, (c) the highest occupied subshell for bromine and (d) the number of electrons in it, and (e) the highest occupied subshell for krypton and (f) the number of electrons in it?

Excited sodium atoms emit two closely spaced spectrum lines called the sodium doublet(Fig. 40-27) with wavelengths 588.995 nm and 589.592 nm. (a) What is the difference in energy between the two upper energy levels (n = 3, I = 1)? (b) This energy difference occurs because the electron’s spin magnetic moment can be oriented either parallel or anti-parallel to the internal magnetic field associated with the electron’s orbital motion. Use your result in (a) to find the magnitude of this internal magnetic field.
