Study Notes
D-Block Elements
- D-block elements are elements in groups 3-12 of the periodic table.
- These elements are also known as transition metals.
Characteristics of D-Block Elements
- The most stable oxidation state of a transition element is +2 or +3.
- D-block elements exhibit a change in properties compared to s-block and p-block elements, such as multiple oxidation states and the ability to form colored ions.
Electron Configuration
- The electron configuration of Cu2+ (Cupric ion) is [Ar] 3d9.
- The electron configuration of Cu in its ground state is [Ar] 3d10 4s1.
Position in the Periodic Table
- D-block elements are located in the d-block section of the periodic table, which is between the s-block and p-block sections.
- They are in groups 3-12 of the periodic table.
Oxidation States
- The oxidation state of Cu2+ (Cupric ion) is +2.
