Interpretation:
The number of electrons present in the highest occupied energy level of 5A is to be determined.
Concept Introduction :
The electron configuration of an element defines how its electrons are arranged throughout its atomic orbitals. Standard notation is used to represent atomic electron configurations, placing all electron-containing atomic subshells in sequential order. The number of electrons held by the subshell is indicated by superscript.
Answer to Problem 16LC
5 electrons
Explanation of Solution
The group is assigned to the element based on its electronic configuration. For, s-block and p-block elements, the no. of electrons present in the highest occupied energy shell represents its group.The s-block includes 1A, 2A, and helium. The p-block includes 3A, 4A, 5A, 6A, 7A, and 8A.
So, group 5A belongs to the p-block element. And its highest occupied energy level contains 5 electrons.
