kleid für standesamt: Periodic Table Information

Periods. Each row in the periodic table is known as a period. Properties vary across a period: In the same period, an element will have a larger atomic radius the farther left in the table it is. Ionization energy, the amount of energy needed to take an electron away from an atom, gets bigger the farther right an element is in the table.

Holmium - Wikipedia

Holmium is a chemical element with the symbol Ho and atomic number 67. Part of the lanthanide series, holmium is a rare-earth element.. Holmium was discovered through isolation by Swedish chemist Per Theodor Cleve and independently by Jacques-Louis Soret and Marc Delafontaine who observed it spectroscopically in 1878. Its oxide was first isolated from rare-earth ores by Cleve in 1878.

Abundance of elements in Earth's crust - Wikipedia

Abundance (atom fraction) of the chemical elements in Earth's upper continental crust as a function of atomic number. The rarest elements in the crust (shown in yellow) are not the heaviest, but are rather the siderophile (iron-loving) elements in the Goldschmidt classification of elements. These have been depleted by being relocated deeper into the Earth's core.
