Question
Find the correlation:
Group 13 to 18 : p block : : ______ : d block
Advertisements
Solution
Group 13 to 18 : p block : : Group 3 to 12 : d block
Explanation:
The d-block in the Modern Periodic Table consists of Groups 3 to 12. These elements are referred to as "transition elements" because they act as a bridge between the highly electropositive s-block metals and the electronegative p-block non-metals. In these elements, the last electron enters the d-orbital of the penultimate shell.
