Everything You'll Have Covered

Which elements are included in the Group IIIA elements?

~ The elements included in the Group IIIA elements are boron, aluminum, gallium, indium, and thallium.

What is unique about thallium in comparison to the other Group IIIA elements?

~ Thallium is the most metallic element and loses the valence electron in its p-orbital and becomes an ion with a +1 charge. Other Group IIIA elements have a +3 valence number because they lose their three valence electrons.

What uses do the Group IIIA elements have?

~ Boron is used to make soap, detergent, and fiberglass. Aluminum is an inexpensive metal used in the production of airplanes and bikes. Gallium is often used in thermometers because of its ultra-low melting point.
