V. A of p orbital can accommodate a maximum of 2 electrons. 7) _______ A) I, II, and IV B) II and IV C) I, II, IV, and V D) II, III, and V E) I, III, and IV

Answer 1

The quantized property of an electron is energy; the maximum number of electrons in a shell is given by 2n²; and for n=4, the maximum number of electrons is 32. The correct statements regarding electron configuration are I, II, IV, and V.

The quantized property of an electron in question 4 is C) energy. Energy levels are quantized, meaning electrons can only exist at specific energy levels within an atom.

In question 5, the maximum number of electrons found in a shell is B) is equal to 2n2. This formula allows us to calculate the maximum number of electrons that can occupy a given shell.

The maximum number of electrons in the n = 4 shell for question 6 is B) 32, which is calculated using the formula 2n2, where n is the principal quantum number of the shell.

For question 7, the true statements are C) I, II, IV, and V. Statement I is true since an f subshell contains 7 orbitals, statement II is accurate because the third energy shell has no f orbitals, statement IV is correct as the second energy shell contains only s and p orbitals, and statement V is true as a p orbital can accommodate a maximum of 2 electrons. The incorrect statement is III since there are only five d orbitals in a d subshell, not ten.
