(a)
Interpretation: The element having the outermost electron in
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.
(a)
Answer to Problem 69A
Element is francium
Explanation of Solution
Given outermost electronic configuration is,
The last electron enters
Thus, the element is Francium (Fr) having electronic configuration 87. Its electronic configuration is,
(b)
Interpretation: The element in which only one electron is present in the d orbital is to be identified.
