Why are Group 3 elements called?
Three valence electrons have group 3 components. Elements of Group 3 will react by losing 3 electrons. A complete shell of 8 electrons is revealed as the 3 electrons are missing, providing more stable conditions. It is said that elements that fall into group 3 are part of the boron group.
What are Group 3 elements used for?
Less Common Group 3 Element-Containing Compounds Although less common than compounds containing boron and aluminum, gallium is a group 3 element that finds use in the field of semiconductors, electronics, and is also used to make metal alloys that have low melting points.
What is Group 4 called?
Group 4 is the second group of transition metals in the periodic table. It contains the four elements titanium (Ti), zirconium (Zr), hafnium (Hf), and rutherfordium (Rf). The group is also called the titanium group or titanium family after its lightest member. All the group 4 elements are hard, refractory metals.
What are elements in Groups 1/3 called?

What is the use of boron element?
Amorphous boron is used as a rocket fuel igniter and in pyrotechnic flares. It gives the flares a distinctive green colour. The most important compounds of boron are boric (or boracic) acid, borax (sodium borate) and boric oxide. These can be found in eye drops, mild antiseptics, washing powders and tile glazes.
What is aluminium commonly used for?
It is soft and malleable. Aluminium is used in a huge variety of products including cans, foils, kitchen utensils, window frames, beer kegs and aeroplane parts.
What are Group 4 metals called?
Group 4 is the second group of transition metals in the periodic table. It contains the four elements titanium (Ti), zirconium (Zr), hafnium (Hf), and rutherfordium (Rf). The group is also called the titanium group or titanium family after its lightest member.
What is group IVA?
Group 4A (or IVA) of the periodic table includes the nonmetal carbon (C), the metalloids silicon (Si) and germanium (Ge), the metals tin (Sn) and lead (Pb), and the yet-unnamed artificially-produced element ununquadium (Uuq).
What are the names of the Group 3 elements?
>> In current IUPAC nomenclature, the elements in group 3 of the periodic table are scandium (Sc), yttrium (Y), lutetium (Lu) and lawrencium (Lr).
What are the metals in the Group 3A?
Group 3A (or IIIA) of the periodic table includes the metalloid boron (B), as well as the metals aluminum (Al), gallium (Ga), indium (In), and thallium (Tl). Boron forms mostly covalent bonds, while the other elements in Group 3A form mostly ionic bonds. The Group 3A metals have three valence electrons in their highest-energy orbitals (ns2p1).
What kind of compounds are in Group 1?
For example, the elements in group 1 (the first column) form compounds that consist of one atom of the element and one atom of hydrogen. These elements (except hydrogen) are known as alkali metals, and they all have similar chemical properties.
How many valence electrons does Group 3A have?
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.
