Where are the rare earth metals on the periodic table?
The rare earths are 17 metallic elements, located in the middle of the periodic table (atomic numbers 21, 39, and 57–71). These metals have unusual fluorescent, conductive, and magnetic properties—which make them very useful when alloyed, or mixed, in small quantities with more common metals such as iron.
What are Groups 3 12 on the periodic table?
The elements in groups 3-12 are called the transition metals. They can form cations of different charges (depending on the metal), with the most common being +2, +3, and +4. The elements in these groups form the d-block, and the partially-filled d-orbitals allow these metals form colourful compounds.
What is the rare earth element in Period 4?
Nickel
Nickel (Ni) is an element in group 10. Nickel is rare in the Earth’s crust, mainly due to the fact that it reacts with oxygen in the air, with most of the nickel on Earth coming from nickel iron meteorites. However, nickel is very abundant in the Earth’s core; along with iron it is one of the two main components.
How many rare-earth metals are in the periodic table?
seventeen metallic elements
The rare earth elements (REE) are a set of seventeen metallic elements. These include the fifteen lanthanides on the periodic table plus scandium and yttrium. Rare earth elements are an essential part of many high-tech devices.

What are the rare earth elements called?
Lanthanide series
Rare Earths are a group of 15 elements in the periodic table known as the Lanthanide series, plus Yttrium. Rare earths are categorised into light elements (lanthanum to samarium) and heavy elements (europium to lutetium). The latter are less common and consequently more expensive.
How many rare earth metals are in the periodic table?
What is period 5 on the periodic table?
The period 5 transition metals are yttrium (Y), zirconium (Zr), niobium (Nb), molybdenum (Mo), technetium (Tc), ruthenium (Ru), rhodium (Rh), palladium (Pd), silver (Ag), and cadmium (Cd).
What element is in group 4 Period 5?
Zirconium
The symbol of the element in Group 4 and Period 5 is Zr. It is the symbol of Zirconium.
How many rare elements are there in the periodic table?
seventeen
Rare earth elements are a set of seventeen chemical elements in the periodic table, specifically the fifteen lanthanides plus scandium and yttrium.
What element is in period 16 Group 14?
carbon group element, any of the six chemical elements that make up Group 14 (IVa) of the periodic table—namely, carbon (C), silicon (Si), germanium (Ge), tin (Sn), lead (Pb), and flerovium (Fl).
Which element is in group 14 period 5?
Tin
Tin. Tin is a chemical element with the symbol Sn (for Latin: stannum) and atomic number 50. It is a main-group metal in group 14 of the periodic table.
Why is Group 14 called the carbon family?
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).
