Question 18 of 25 4.0/ 4.0 Points Which of the following have the same number of valence electrons? A. In, Pb, Bi B. Cs, Bi, At C. N, P, As D. Xe, Rn, At
Feedback: See Chapter 06 Question 19 of 25 4.0/ 4.0 Points What is the ground state electron configuration for Zr 2+ ?
Feedback: See Chapter 06 Question 20 of 25 4.0/ 4.0 Points How many subshells are there in the shell with n = 6?
Feedback: See Chapter 06 Question 21 of 25 0.0/ 4.0 Points Of the following, which element has the highest first ionization energy?
Feedback: See Chapter 06 Question 22 of 25 4.0/ 4.0 Points Give the principal level for a 2 p sublevel. A. 0 B. 1 C. -2 D. -1 E. 2 Feedback: The principal quantum number n corresponds to the shell in which the electron is located. Thus n can therefore be any integer. For example, an electron in the 3s subshell has a principal quantum number of n=3 because 3s is in the second shell.
