Question

( begin{array}{l}text { atomic mas }left{A^{prime} Aright. text { tomic no. } angle zend{array} quad A^{A-4} B+P P^{4} rightarrow alpha- ) particle
( A_{B}^{-4} B^{A-4}+2 beta rightarrow e^{-} )
( 2-2^{2} C^{2} )
Hemce C have same atomic number so they're isotopes

# 22. Element A, decay in C by following two stene AB+ Het B+C+ 2B (1) A and B are isobars I (2) A and Care isotopes (3) A and C are isobars (4) A and Care isodiaphers
