Plutonium At Room Temperature

Plutonium atoms have 94 electrons and 94 protons with 2 valence electrons in the outer shell.

Plutonium at room temperature. What state of matter is plutonium at room temperature. Plutonium normally has six allotropes and forms a seventh zeta ζ at high temperature within a limited pressure range. At room temperature plutonium is in its alpha α form the most common structural form of the element. Plutonium is a member of the actinide group in the periodic table.

Plutonium expands up to 70 in volume as it oxidizes and thus may break its container. 19 84 grams per cubic centimeter. It is as hard and brittle as cast iron unless alloyed with other metals to form the room temperature stabilized delta δ phase which makes it soft and ductile. At room temperature alpha form plutonium is as hard and brittle as cast iron.

The radioactivity of the burning material is an additional hazard. Plutonium in the δ phase delta phase normally exists in the 310 c to 452 c range but is stable at room temperature when alloyed with a small percentage of gallium aluminium or cerium enhancing workability and allowing it to be welded in weapons applications. Divided metal at room temperature puo2 readily reacts to form plutonium dioxide. Non divided metal at room temperature corrodes relatively inert slowly oxidizes.

913 k 640 c or 1184 f boiling point. It can be alloyed with other metals to form the room temperature stabilized delta form which. It can be alloyed with other metals to form the room temperature stabilized delta form which is soft and ductile. Unlike most metals it is not a good conductor of heat or electricity.

The delta phase has more typical metallic character and is roughly as strong. Scientists have found that they can mimic this effect by adding a small amount of gallium which gives the room temperature metal similar properties to its higher temperature counterpart and this. Spontaneously ignites at. At room temperature for instance the plutonium is very brittle but heated to around 100 celsius is transforms to a much more malleable metal.

3501 k 3228 c or 5842 f density. At room temperature alpha form plutonium the most common form is as hard and brittle as cast iron. Characteristics and properties under standard conditions plutonium is a hard brittle silvery metal. 2009 06 14 21 11 27 2009 06 14 21 11 27.

There are 150 neutrons in the most abundant isotope. Phase at room temperature. 94 pu plutonium 244.
