Atomic mass is the mass of an individual atom, whereas atomic weight ciencja the average weighted of the atomic masses of an atom’s naturally occurring isotopes. On the basis of these data, confirm that the average atomic weight of Cr is On this basis, how many atoms are there in a pound-mole of a substance?

The n quantum number designates the electron shell.

The l quantum number designates the electron subshell. The ml quantum number designates the number of electron states in each electron subshell. The ms quantum number designates the spin moment on each electron.

The relationships between n and the materuais designations are noted in Table 2. For the K shell, the four quantum numbers for each of the two electrons in the 1s state, in the order of nlmlms, are.

Write the four quantum numbers for all of the electrons in the L and M shells, and note which correspond to the s, p, and d subshells. Possible l values are 0, 1, and 2; possible ml values are. Solution The electron configurations for the ions are determined using Table 2.

In order to become an ion with a plus two charge, it must lose two electrons—in this case the two 4s. In order to become an ion with a plus three charge, it must lose three electrons—in this case two 3s and the one 3p. In order to become an ion with a plus one charge, it must lose one electron—in this case the 4s. The atomic number for barium is 56 Figure 2.

In order to become an ion with a plus two charge, it must lose two electrons—in this case two the 6s. In order to become an ion with a minus one charge, it must acquire one electron—in this case another 4p.

Thus, the electron configuration for a Br- ion is 1s22s22p63s23p63ds24p6. In order to become an ion with a minus two charge, it must acquire two electrons—in this case another two 2p. Ods, the electron configuration for an O2- ion is 1s22s22p6. The Cl- ion is a chlorine atom that has acquired one extra electron; therefore, it has an electron configuration the same as argon.

From the periodic table Figure 2. According to Figure 2. Moving four columns to the right puts element under Pb and in group IVA. The attractive force between two ions FA is just the derivative with respect to the interatomic separation of the attractive energy expression, Equation 2. The constant A in ciiencia expression is defined in footnote 3. Calculate the bonding energy E0 in terms of the parameters A, B, and n using the following procedure: Differentiate EN with respect to r, and then set the resulting expression equal to zero, since the curve of.

EN versus r is a minimum at E0. Solve for r in terms of A, B, and n, which yields r0, the equilibrium interionic spacing. Determine the expression for E0 by substitution of r0 into Equation 2.

Solution Atomic mass is the mass of an individual atom, whereas atomic weight is the average weighted of the atomic masses of an atom’s naturally occurring isotopes.
