What classification is terbium?
Terbium is a chemical element with symbol Tb and atomic number 65. Classified as a lanthanide, Terbium is a solid at room temperature.
What is the family group of carbon?
Group 14 is the carbon family. The five members are carbon, silicon, germanium, tin, and lead. All of these elements have four electrons in their outermost energy level. Of the Group 14 elements, only carbon and silicon form bonds as nonmetals (sharing electrons covalently).
What is terbium on the periodic table?
Terbium (Tb) is a chemical element with atomic number 65 represented with the symbol Tb in the periodic table, which was discovered by Carl Mosander in the year 1843. It is named after the village of Ytterby in Sweden. Terbium is a soft, ductile, malleable and very rare element.
What family is terbium?
lanthanide series
terbium (Tb), chemical element, a rare-earth metal of the lanthanide series of the periodic table.
What group is terbium in?

Is terbium an actinide?
The electronic configuration of terbium is [Xe]4f96s2 as here last electron is entering in the 4f orbital so, it is not an actinide. it is lanthanide.
Where are the carbon family on the periodic table?
group 14
The carbon group is a periodic table group consisting of carbon (C), silicon (Si), germanium (Ge), tin (Sn), lead (Pb), and flerovium (Fl). It lies within the p-block. In modern IUPAC notation, it is called group 14. In the field of semiconductor physics, it is still universally called group IV.
Is terbium a metal or nonmetal?
Terbium is a soft, malleable, ductile, silver-gray metal member of the lanthanide group of the periodic table.
Is terbium a metal nonmetal or metalloid?
Terbium is a chemical element with the symbol Tb and atomic number 65. It is a silvery-white, rare earth metal that is malleable, and ductile.
Why is terbium not actinide?
What is carbon group also called?
The group 14 elements are the second group in the p-block of the periodic table. It is also called the carbon group. The members of this group are: Carbon (C) Silicon (Si)
What are the properties of terbium?
Terbium is a soft, malleable, ductile, silver-gray metal member of the lanthanide group of the periodic table. It is reasonably stable in air, but it is slowly oxidised and it reacts with cold water. Terbium is rare and expensive, so it has few commercial uses.
Where can you find terbium?
It is never found in nature as free element, but is is contained in many minerals. The most important ore are monazite, bastnasite and cerite. The main mining areas are China, USA, India, Sri Lanka, Brazil and Australia and reserves fo terbium are estimated to be around 300.000 tonnes.
Is carbon a metal nonmetal or metalloid?
nonmetal
Carbon is a nonmetal, and the remaining elements in this group are metals. Group 15 is called the nitrogen group. The metalloids in this group are arsenic and antimony. Group 15 also contains two nonmetals and one metal.
