Question
Chapter 1, Problem 1.5PAE
Interpretation Introduction
Interpretation:
The region of the periodic table where critical materials are found should be identified.
Concept Introduction:
- Critical materials are rare earth metals
- There are different regions in the periodic table mainly depending on the chemical similarity of elements in a particular area.
- Depending on the type of sub shell which receives the last electron, elements have been classified into four periodic table blocks (s, p, d and f)
