It emits a "beta particle," which is simply an electron. Cf-251's nucleus contains 153 neutrons. One of them spontaneously becomes a proton and an electron. The new proton bumps up its atomic number by 1, so it becomes Es-251. The overall mass is unchanged. The electron, or beta particle, is ejected from the nucleus. This is called beta decay.
What else can I help you with?
What happens when californium 251 decays into curium 247?
When californium-251 decays into curium-247, it undergoes alpha decay, releasing an alpha particle (helium nucleus) in the process. This results in the transformation of the nucleus to curium-247 with a simultaneous decrease in atomic number and mass number.
What is the atomic mass of californium?
The atomic number of californium is 98. The atomic mass of the most stable isotope - 251Cf - is (251) after IUPAC.
What is the atomic weight of Californium?
251.
How many stable isotopes are in the element californium?
All the isotopes of californium are radioactive, artificial and unstable.
What is the relative atomic mass of californium?
Californium, with the chemical symbol Cf, is the chemical element with the atomic number 98.
What is the balance nuclear equation for alpha decay of 251 N0?
The balance nuclear equation for the alpha decay of ^251No (Nobelium-251) is: [ ^{251}{102}No \rightarrow ^{247}{100}Fm + ^{4}_{2}\alpha ] In this equation, Nobelium-251 decays into Californium-247 while emitting an alpha particle ((^4_2\alpha)). The mass and atomic numbers are conserved in the reaction.
What is the atomic mass and number for californium?
The atomic number of californium is 98. The atomic mass of the most stable isotope - 251Cf - is (251) after IUPAC.
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.
Is californium an unstable element?
Being radioactive californium is unstable.
What element is named for CA?
Californium, Symbol: Cf, Atomic Number: 98, Atomic Weight: 251
What is the amount of neutrons protons and electrons in californium?
Californium's atomic number is 98. Thus, to be neutral, it must have 98 protons and 98 electrons. 251Cf is its longest lived isotope and has 251 - 98 = 153 neutrons.
What is the equation for decay of californium 251?
251Cf --> 247Cm + 4He 247Cm --> 243Pu + 4He 243Pu --> 243Am + e- 243Am --> 239Np + 4He 239Np --> 239Pu + e- 239Pu --> 235U + 4He 235U --> 231Th + 4He 231Th --> 231Pa + e- 231Pa --> 227Ac + 4He 227Ac --> 223Fr + 4He, 227Th + e- 223Fr --> 219At + 4He, 223Ra + e- 227Th --> 223Ra + 4He 219At --> 215Bi + 4He, 219Rn + e- 223Ra --> 219Rn + 4He 215Bi --> 215Po + e- 219Rn --> 215Po + 4He 215Po --> 211Pb + 4He 211Pb --> 211Bi + e- 211Bi --> 207Tl + 4He, 211Po + e- 207Tl --> 207Pb + e- 211Po --> 207Pb + 4He 207Pb: stable
