41ca decays by electron capture the product of this reaction undergoes alpha decay what is the product of this second decay reaction

in electron capture a protons is converted to neutron and an electron neutrino. therefore the resulting atom will be less by one proton while the atomic mass remain unchanged

₂₀Ca →  ₁₉Ka  + ^-e

 now the potassium undergo a alpha decay, meaning a decrease of two from atomic number and four from mass number.

⁴¹ ₁₉Ka  → ³⁷ ₁₇Cl + ⁴ ₂He

 the of the second decay is chlorine -37
