Which outcome occurs in potassium-40 when electron capture decay transpires?

A)Argon-40 and a neutrino form
B)Calcium-40 and an electron form
C)Potassium-39 and a proton form
D)Argon-39 and a positron form

💡 Explanation

Electron capture causes transformation because the atom absorbs an electron, converting a proton to a neutron via the weak interaction that emits a neutrino; thereby producing Argon-40; therefore, electron emission is not formed, but rather a neutrino.
