It is radioactive.
-------------------------------
Incorrect answer: americium-241, the usual isotope in smoke detectors is more radioactive.
The isotope 242Cm is more expensive than the isotope 241Am.
The Brinell hardness of plutonium is 242, the Vickers hardness is 255.
110kg = 17st 4lb 8.1357 oz.
If he weighs 637 N on Earth, then his mass is 65 kg.
* (e) (i) 214Bi → 214Po + e- + ve * (ii) 38K → 38Ar + e+ + ve * (α) 242Pu → 238U + α++ where α++ = 2p+ + 2n0
About 250 grams.
Curium-242 has 146 neutrons and curium-244 has 148 neutrons. Also the half lives are different.
The first time curium was obtained by the reaction:Pu-239 + He-4 = Cm-242 + nNow curium is obtained from burned nuclear fuels.
The first nuclear reaction to obtain curium was:Pu-239 + He-4 = Cm-242 + nNow curium is separated from burned nuclear fuels.
The first nuclear reaction to obtain curium was:Pu-239 + He-4 = Cm-242 + nNow curium is separated from burned nuclear fuels.
The specific activity of the isotope curium-242 is 3 400 Ci/g.
The nuclear reaction used to prepare curium was:Pu-239 + He-4---------------Cm-242 + n
The first nuclear reaction to obtain curium was:Pu-239 + He-4 = Cm-242 + nNow curium is separated from burned nuclear fuels.
The nuclear reaction is: 242Cm + 4He = 245Cf + n
The nuclear reaction is: 242Cm + 4He = 245Cf + n
Americanium
The nuclear reaction is: 242Cm + 4He = 245Cf + n
Possible uses for thermoelectric generators (Cm 242 and Cm 244); now these isotopes has some disadvantages.
