Curium is a radioactive element with atomic number 96 and element symbol Cm. This WebElements periodic table page contains physical properties for the element curium Get … Solid at standard temperature (20 o C). Its radiation destroys bone marrow preventing red blood cell production. Curium is a transuranic radioactive chemical element with the symbol Cm and atomic number 96. Atmospheric testing of nuclear weapons, which ceased worldwide by 1980, generated most environmental curium. Know everything about Curium Facts, Physical Properties, Chemical Properties, Electronic configuration, Atomic and Crystal Structure. The number of electrons in each of curium's shells is 2, 8, 18, 32, 25, 9, 2 and its electron configuration is [Rn] 5f 7 6d 1 7s 2. Most compounds of trivalent curium are stable and faintly yellow or yellow-green.

However, more energy is required to add an electron to a negative ion which overwhelms any the release of energy from the electron attachment process.

In its elemental form, curium's CAS number is 7440-51-9.

On the other hand neon, the noble gas, immediately preceding it in the periodic table, requires 2081 kJ/mol or 21.56 eV/atom.The liquid phase has a higher internal energy than the solid phase. Relative atomic mass The mass of an atom relative to that of carbon-12. It was produced by the bombardment of alpha particles on plutonium Pu-239 using the 60 inch cyclotron [1]. The physical properties of curium include a boiling point of 1,340°C (2,444°F), and a melting point of 3,110°C (5,630°F). It is present in nature in areas where nuclear tests were conducted.


Because of its high radioactivity curium should be handled with care. Curium is highly radioactive. The amount is however neglible and its radiation contribute only a thiny fraction of the Eartch's background radiation.

Get …
Consequently, curium is considered very toxic.Stay up to date on the coronavirus outbreak by signing up to our newsletter today.©Future US, Inc. 11 West 42nd Street, 15th Floor,New York,NY 10036. Curium is a Block P, Group 3, Period 7 element. The ground state electronic configuration of neutral curium is [Rn].5f 7.6d 1.7s 2 and the term symbol of curium is 9 D 2.. Curium: description Your user agent does not support the HTML5 Audio element. Its radiation destroys red blood cell formation. Gastrointestinal absorption from food or what is the most likely source of any internally deposited curium in the general population. Because curium is taken up in the body much more readily if inhaled rather than ingested, both exposure routes can be important. It is present in nature in areas where nuclear tests were conducted. T Seaborg at University of California, Berkeley in 1944. Curium is a synthetic radioactive element that was first produced in laboratory.

Curium is formed in nuclear reactors i…

When an electron is added to a neutral atom, energy is released. Curium | Cm | CID 23979 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more. Some of these electrons are more tightly bound in the atom than others.
