Potassium- 40 decays in three different ways: about 10 per cent decays to Ar 18 40 by electron capture. Suggest how this process might be described using a nuclear equation.

Electron capture is the transformation of an atomic nucleus in which an electron from the atom is spontaneously absorbed into the nucleus. There is a decrease in atomic number by one. K 19 40 + e - 1 0 → Ar 18 40 + γ
