It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas, the first in the noble gas group in the periodic table. Americium is a transuranic member of the actinide series, in the periodic table located under the lanthanide element europium, and thus by analogy was named after the Americas. Irvine, CA 92614 Below the boiling point, the liquid is the more stable state of the two, whereas above the gaseous form is preferred. Actinium gave the name to the actinide series, a group of 15 similar elements between actinium and lawrencium in the periodic table. Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal. The melting point of ice is 0 C. Tungsten is an intrinsically brittle and hard material, making it difficult to work. Nickel belongs to the transition metals and is hard and ductile.
