# Write Nuclear Reaction Equations for β+-decay of 9743tc - Physics

Write nuclear reaction equations for β+-decay of ""_43^97Tc

#### Solution

α is a nucleus of helium (""_2He^4) and β is an electron (e− for β− and e+ for β+). In every α-decay, there is a loss of 2 protons and 4 neutrons. In every β+-decay, there is a loss of 1 proton and a neutrino is emitted from the nucleus. In every β−-decay, there is a gain of 1 proton and an antineutrino is emitted from the nucleus.

For the given cases, nuclear reactions can be written as:

""_43^97 Tc -> _42^97Mo + e^+ + v
