Study Notes
Transition Metals in Chemistry
- A transition metal is defined as an element that has a partially filled d subshell or can form ions with a partially filled d subshell.
Classification of La and Ac
- La (Lanthanum) and Ac (Actinium) are sometimes classified as transition metals due to their ability to form ions with a partially filled d subshell, similar to the other transition metals.
Electronic Configurations of Transition Metals
- The electronic configuration that indicates a transition metal is one that has a partially filled d subshell, such as d1-10.
f-Block Elements
- The series of elements that are classified as f-block elements are the Lanthanides and Actinides, which include the elements with atomic numbers 57-71 and 89-103, respectively.
Valence Electronic Structure of Transition Metals
- The typical valence electronic structure of transition metal atoms is ns2 (n-1)d1-10, where n is the principal quantum number of the valence shell.
