The number of beta particles emitted by a radioactive substance is twice the number of alpha particles emitted. The resulting daughter is an
Options
(a) isomer of parent
(b) isotone of parent
(c) isotope of parent
(d) isobar of parent
Correct Answer:
isotope of parent
Explanation:
Isotopes of an element have the same atomic number but different mass number. A radioactive substance when emits one alpha particles (₂He⁴), its mass number reducesby 4 and charge mo. reduces by 2 and after emissin of two β – particles its charge no. increase by 2 thus the charge no. i.e., atomic number remains the same.
