Representative Elements and Transition elements
The periodic table’s groups 1 and 2, as well as groups 13 to 18, contain the representative elements.
In other words, the terms “representative elements” refer to both s-block and p-block elements collectively.
The term “representative elements” refers to elements with complete inner shells but incomplete outer shells, i.e., substances with fewer than 8 electrons in the outermost shell. Except for inert gas, the s and p – block elements are known as representative elements.
Transition elements also known as transition metals.
Types of Transition Elements
Transition elements are of two types
1. Inner transition elements
2. Outer transition elements
Inner transition elements
Inner transition elements are those where the final electron enters the f-orbital and are called inner transition elements.
Outer transition elements
Outer transition elements are those where the final electron enters the d-orbital and are called outer transition elements.
What is the difference between transition metals and representative metals?
Representative elements are chemical elements in groups 1, 2, and 13–18, whereas transition elements are chemical elements in groups 3–12, including Lanthanides and Actinides. This is the main difference between representative elements and transition elements.
