Determine the missing products to complete the given decay scheme: ¹⁹₈ O ¹⁹₉ F + ,?

Options

Ae⁺ +
Be⁺ +
Ce⁻ +
De⁻ +

Correct answer

C. e⁻ +

Step-by-step solution

The given decay scheme is ¹⁹₈ O ¹⁹₉ F + ,? In this process, the atomic number Z increases by 1 (from 8 to 9 ) while the mass number A remains unchanged ( 19 ). This indicates a ⁻ decay, where a neutron is converted into a proton, an electron ( e⁻ ), and an antineutrino ( ). The fundamental nuclear reaction is n p + e⁻ + . Thus, the missing products are e⁻ and .
