A
d-block
B
p-block
C
s-block
D
f-block
Verified step by step guidance1
Recall that the periodic table is divided into blocks based on the electron configuration of the elements, specifically which subshell is being filled with electrons.
Identify the electron configuration of manganese (Mn), which has an atomic number of 25. The configuration ends in the 3d subshell because it is a transition metal.
Understand that elements filling the d subshell are classified as d-block elements, which are typically transition metals located in groups 3 to 12 of the periodic table.
Since manganese's valence electrons are in the 3d subshell, it belongs to the d-block of the periodic table.
Therefore, by analyzing the electron configuration and the position of manganese, you can conclude that manganese is a d-block element.
