What are alkali metals used for?
Soft, silvery-white alkali lithium is the lightest metal and the lightest solid element. Highly reactive and flammable, lithium has to be stored in mineral oil. Industrial applications include heat-resistant glass and ceramics, lithium grease lubricants, flux additives for iron, steel and aluminium production.
Where is Group 3 on the periodic table?
transition metals
Group 3 is the first group of transition metals in the periodic table.
What is Group 3 on the periodic table called?
Transition Metals
The elements from Group 3 to 12 are called Transition Metals. They include the Scandium, Titanium, Vanadium, Chromium, Manganese, Iron, Cobalt, Nickel, Copper, and Zinc families of elements. Transition Metals are hard and dense, are good conductors of heat and electricity, and can be bent easily.
What are the 4 main groups on the periodic table?
Elements can be classified as metals, metalloids, and nonmetals, or as a main-group elements, transition metals, and inner transition metals. Groups are numbered 1–18 from left to right.

What are the properties of Group 3?
The Group 3A metals have three valence electrons in their highest-energy orbitals (ns2p1). They have higher ionization energies than the Group 1A and 2A elements, and are ionized to form a 3+ charges. The Group 3A metals are silvery in appearance, and like all metals are good conductors of electricity.
