Holmium
Holmium is a chemical element with the symbol Ho and atomic number 67. It is a rare earth metal that is found in the monazite and bastnasite ores. Holmium is a soft, malleable, and ductile metal that tarnishes slowly in the air. It has a pinkish-white tinge that can be seen in its oxide form. Holmium is a chemical element that has the symbol Ho and atomic number 67. It is a rare earth metal and is silvery-white in color. It is soft enough to be cut with a knife and has a density of 8.9 g/cm3. It is a relatively stable element and does not corrode in air. It is found in small amounts in the earth’s crust and is mostly used in the production of lasers.
Isotopes
There are three naturally occurring isotopes of holmium: holmium-165, holmium-166, and holmium-167. All of these isotopes are radioactive. Holmium-165 has a half-life of 1.39 million years, holmium-166 has a half-life of 3.01 million years, and holmium-167 has a half-life of 1.08 billion years
Properties
Holmium has a number of interesting properties. It is the most magnetic of all the elements and has a high thermal neutron absorption cross-section. It is also the element with the highest ionization energy. Holmium has a number of applications in the industry. It is used in lasers, in the production of alloys, and as a dopant in the glass.
Structure
Holmium is a valuable element and is currently worth about $200 per ounce. It is not widely used, but its properties make it a valuable commodity. It is important to understand the chemistry of holmium and the other elements in the lanthanide series in order to be able to use them effectively in the industry.
Holmium is a rare-earth metal that was first identified in 1878 by Swedish chemist Per Teodor Cleve. It has the symbol Ho and atomic number 67. Holmium is a silver-white metal that is relatively soft and has a high melting point. It is a good conductor of heat and electricity and is relatively stable in air.
