Question

The group, period, and block of the elements with the following electron configuration

[Ar]4s² 3d¹⁰ 4p² are:

- Group 4, period 4, block
- Group 14, period 4, block
- Group 4, period Z, block
- None of the above

Answer 1

The correct answer is that the element with the electron configuration [Ar]4s² 3d¹⁰ 4p² is located in Group 14, Period 4, and the p-block of the periodic table. The correct answer for this question form the given options is option B.

Step-by-step explanation:

The electron configuration [Ar]4s² 3d¹⁰ 4p² corresponds to an element in Group 14, Period 4, and the p-block of the periodic table. Group 14 includes carbon and its heavier congeners, all of which have four electrons in their outermost p orbital. The period number corresponds to the highest principal quantum number, which is 4 in this case. The block indicates which subshell is being filled; for the p² configuration, the p-block is the correct category.
