The lanthanide, or lanthanoid, series. This is a classification on the Periodic Table characterized by shared properties of these elements, for example, Holmium and Praseodymium have similar properties. Lanthanide is prefered by the public, lanthanoid is preferred by scientists of IUPAC (International Union of Pure and Applied Chemistry).
Holmium is in the lanthanoid series.
Holmium (Ho) is a member of the lanthanides family.
Holmium is a rare earth metal.
All of the praseodymium ordinarily found in nature is of a single stable isotope, 141Pr. Like all other elements, there are synthetic radioactive isotopes of praseodymium.
HO is Holmium. It is a part of the Lanthanides Series. It's atomic number is 67.
The element with 67 electrons is Holmium (Ho). Holmium is a Lanthanide and so, is in Period 6 of the Periodic Table. It's atomic number is 67. Holmium has 67 electrons in 6 shells with 2 electrons in the outer shell.
Praseodymium is a solid metal.
Holmium's abreviation is Ho
Praseodymium is a chemical element !
Lithium is an element, however "Holmium" is not you may be mistaking Holmium for Helium though
"Ho" in the periodic table refers to the element holmium. Holmium is a rare earth metal with the atomic number 67 and is part of the lanthanide series. It is primarily used in magnetic applications and as a component in certain types of lasers.
Praseodymium has six electron shells.
