Question

The following disintegration reactions are

i) _zX^A → _{Z -2}Y ^A + α

ii) _zX^A → _{Z -1}P^A + β

• A. i) allowed and ii) not allowed
• B. i) not allowed and ii) notallowed
• C. i) not allowed and ii) allowed
• D. i) allowed and ii) allowed
• E. Depend on temperature and pressure conditions

Answer 1

The correct option is B

i) not allowed and ii) notallowed

Not correct as mass number should have reduced by 4 and not remained the same on Alpha emission

Not correct as the atomic number should have increased by 1 and not decreased by 1 on Beta emission
