The elements in the third group of the Periodic Table are boron, aluminum, gallium, indium, and thallium. These elements have similar chemical properties due to their shared position in the periodic table. They are commonly referred to as Group 13 elements.
Tantalum
There are eight third period transition elements on the periodic table.
Argon belongs to the noble gas group (Group 18) on the periodic table.
The third row of the periodic table contains elements with 3p electrons. Some examples of elements in this row are phosphorus, sulfur, and chlorine.
