(a)
Interpretation:Element is to be identified as representative elements,
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 15LC
Noble gas
Explanation of Solution
The given electronic configuration is,
The outer shell contains 8 electrons, so its octet is complete. Thus, it is a noble gas.
(b)
Interpretation:Element is to be identified as representative elements, transition elements, or noble gas.

Answer to Problem 15LC
Transition element
Explanation of Solution
The given electronic configuration is,
The last enters into d-subshell thus, it is a transition metal.
(c)

(c)
Answer to Problem 15LC
Representative element
Explanation of Solution
The given electronic configuration is,
The outermostelectrons enterthe p-subshell. So, it is a p-block element. The p-block element is called a representative element.
Thus, the given electronic configuration belongs to a representative element.
