The nucleus _48Cd^115, after two successive -decay will give

the nucleus 48cd pow 115 after two successive beta decay

The nucleus $$_{48}C{d^{115}},$$ after two successive $$\beta $$-decay will give

A. $$_{46}P{a^{115}}$$

B. $$_{49}I{n^{114}}$$

C. $$_{50}S{n^{113}}$$

D. $$_{50}S{n^{115}}$$

Answer : $$_{50}S{n^{115}}$$

Solution :
When a parent nucleus emits a $$\beta $$-particle (i.e, an electron) mass number remains same because mass of electron is negligibly low. Atomic number is increased by one. The nucleus $$_{48}C{d^{115}}$$ after two successive $$\beta $$-decays will give $$_{50}S{n^{115}}.$$
