What is produced when mercury 201 undergoes electron capture?

What is produced when mercury 201 undergoes electron capture?

Write nuclear equations for the following processes: (a) Mercury-201 undergoes electron capture; (b) thorium-231 decays to form protactinium-231. Because the mass numbers must have the same sum on both sides of the equation, 201 + 0 = A.

What is the equation for beta decay?

The β+ decay equation is AZXN→AZ−1YN+1+β++νe Z A X N → Z − 1 A Y N + 1 + β + + ν e .

What is β decay give an example?

For example, beta decay of a neutron transforms it into a proton by the emission of an electron accompanied by an antineutrino; or, conversely a proton is converted into a neutron by the emission of a positron with a neutrino in so-called positron emission.

What is the correct equation for the decay of polonium-210?

Polonium-210, 210Po, decays to lead-206, 206Pb, by alpha emission according to the equation 84Po210 → 82Pb206 + 2He4 If the half-life, t1/2, of 210Po is 138.4 days, calculate the mass of 206Pb produced from a 574.0 mg sample of Polonium(IV) chloride, PoCl4, that is left untouched for 333.5 days.

What would happen if radium 226 undergoes alpha decay?

After undergoing alpha decay, an atom of radium 226 becomes radon 222.

What is emitted in a beta decay?

In electron emission, also called negative beta decay (symbolized β−-decay), an unstable nucleus emits an energetic electron (of relatively small mass) and an antineutrino (with little or possibly no rest mass), and a neutron in the nucleus becomes a proton that remains in the product nucleus. …

What is emitted from beta-minus decay?

In electron emission, also called negative beta decay (symbolized β−-decay), an unstable nucleus emits an energetic electron (of relatively small mass) and an antineutrino (with little or possibly no rest mass), and a neutron in the nucleus becomes a proton that remains in the product nucleus.

What element is formed when polonium 210 undergoes alpha decay?

lead-206
alpha decay Thus polonium-210 (mass number 210 and atomic number 84, i.e., a nucleus with 84 protons) decays by alpha emission to lead-206 (atomic number 82).

What will be formed if polonium 210 emits an alpha particle?

Polonium-210 has a half-life of 138 days, and it decays to stable lead-206 by emitting an alpha particle (an alpha particle has two protons and two neutrons).

Where does the beta particle in nuclear decay come from?

The beta particle (electron) emitted is from the atomic nucleus and is not one of the electrons surrounding the nucleus. Such nuclei lie above the band of stability. Emission of an electron does not change the mass number of the nuclide but does increase the number of its protons and decrease the number of its neutrons.

What happens when cobalt-59 undergoes a beta decay?

When cobalt-59 undergo a beta decay, the atomic number increases by one while the mass number remain unchanged, during a beta decay, a neutron decays into a proton, an electron and an electron antineutrino. For a positron decay of cobalt-5, the atomic number of the beryllium decreases by one while the mass number will remain unchanged.

What happens to the atomic number of beryllium during a beta decay?

When beryllium undergo a beta decay, the atomic number increases by one while the mass number remain unchanged, during a beta decay, a neutron decays into a proton, an electron and an electron antineutrino. For a positron decay of beryllium-8, the atomic number of the beryllium decreases by one while the mass number will remain unchanged.

When does a daughter nuclide decay to its ground state?

Consequently, the n:p ratio is decreased, and the daughter nuclide lies closer to the band of stability than did the parent nuclide. Gamma emission (γ emission) is observed when a nuclide is formed in an excited state and then decays to its ground state with the emission of a γ ray, a quantum of high-energy electromagnetic radiation.
