What is the difference between Curium 242 and Curium 244?
Curium-242 has 122 neutrons and Curium-244 has 124 neutrons. This neutron difference causes them to have different decay pathways and half-lives, with Curium-242 having a shorter half-life than Curium-244.
Who discovered californium 252?
Californium-252 was discovered by a team of scientists led by Albert Ghiorso at the University of California, Berkeley in 1950. They synthesized Californium-252 by bombarding curium-242 with alpha particles.
Which substance present in the atmosphere is responsible for the absorption of solar radiation with a wavelength less than 242 nm?
Oxygen is responsible for the absorption of solar radiation with a wavelength less than 242nm. UV radiation splits oxygen into atoms and the atoms combine with other oxygen molecules to form ozone. Generally, all multi-atom?æ compounds are capable of absorbing UV radiation when the wavelength is short.
What is the luster and hardness of plutonium?
Plutonium is a silvery metal.- Vickers hardness: 255 - Brinell hardness: 242 - Mohs hardness: cca. 3,7
What form of UV radiation is absorbed by O2?
Oxygen absorbs ultraviolet radiation with wavelengths shorter than 242 nm, specifically in the UV-C range. UV-C radiation breaks apart oxygen molecules to form ozone in the stratosphere, which helps protect Earth from harmful UV radiation reaching the surface.
When curium 242 was synthesized by bombarding an isotope with alpha particles 42He what equation would show this reaction?
The synthesis of curium-242 ((^{242}\text{Cm})) by bombarding an isotope with alpha particles ((^{4}\text{He})) can be represented by the following nuclear reaction equation: [ ^{238}\text{Pu} + ^{4}\text{He} \rightarrow ^{242}\text{Cm} + n ] In this equation, plutonium-238 ((^{238}\text{Pu})) is typically the target isotope, and a neutron ((n)) is emitted during the reaction.
When curium -242 is bombarded with alpha particles a neutron and are formed?
The nuclear reaction is: 242Cm + 4He = 245Cf + n
When curium-242 is bombarded with alpha particles a neutron and what are formed?
The nuclear reaction is: 242Cm + 4He = 245Cf + n
When curium-242 is bombarded with alpha particles a neutron and are formed?
The nuclear reaction is: 242Cm + 4He = 245Cf + n
What was combined with alpha particles to create curium 242?
I suppose that the isotope formed is Am-245.
How is element californium obtained?
For the first time californium is obtained with the nuclear reaction:Cm-242 + He--------------Cf-245 + nThe important isotope Cf-252 is obtained in nuclear reactors after a long time irradiation of plutonium with neutrons.
What are the nuclear equations for the following processes bismuth 214 undergoes b-minus decay potassium-38 undergoes b-plus emission plutonium-242 emits radiation?
Bismuth-214 undergoes beta-minus decay: 214Bi --> 214Po + e^- Potassium-38 undergoes beta-plus emission: 38K --> 38Ar + e^+ Plutonium-242 emits radiation: No specific nuclear equation as "emits radiation" is a general statement.
What happens to curium-242 when it's bombarded with an alpha particle?
Depending on the energy of the alpha, fusion into Californium-246 could happen, or elastic Rutherford scattering could happen. If the alpha was energized enough to compensate for the reactions net mass increase (mCf - mCm - mα = 6.86MeV) and the Coulomb barrier (about 26MeV), so about 33MeV total, it could fuse into Cf246. Otherwise it'll bounce off the Cm242 via elastic scattering.
What element was made by bombarding plutonium and alpha particles?
The reaction is:Pu-239 + alpha = Cm-242 + n
When curium-242 is bombarded with an alpha particle two products are formed one of which is a neutron what is the other product?
The other product formed when curium-242 is bombarded with an alpha particle is uranium-238.
How can you get curium?
The first nuclear reaction to obtain curium was:Pu-239 + He-4 = Cm-242 + nNow curium is separated from burned nuclear fuels.
When curium 242 is bombarded with alpha particles two products are formed one of these is a neutron what is the other?
I suppose that the isotope formed is Am-245.
