Expert Solution

Step 1

For this question we will use the concept of mass no and atomic no.

we know that,

i)the sum of atomic no of reactant = sum of atomic no of product

ii)the sum of mass no of reactant = sum of mass no of product

Part a)

$f o r g i v e n n u c l e a r r e a c t i o n a t o m i c n o r e a c \tan t p a r t i c l e = a t o m i c n o o f A t + a t o m i c n o o f H e = 85 + 2 = 87 a l s o, m a s s n o r e a c \tan t p a r t i c l e = m a s s n o o f A t + m a s s n o o f H e = 217 + 4 = 221 s o, t h e e l e m e n t w i t h a t o m i c n o 87 a n d m a s s n o 221 i s F r a n c i u m t h e r e f o r e t h e m i s s i n g p a r t i c l e i s {}_{87}^{221}F r (F r a n c i u m)$

$T h e c o m p l e t e r e a c t i o n i s {}_{87}^{221}F r \to {}_{85}^{217}A t + {}_{2}^{4}H e$

For part b)

$f o r g i v e n n u c l e a r d e c a y r e a c t i o n o f P u t h e a t o m i c n o i n c r e a s e s b y 1 t h e m a s s n o r e m a i n u n c h a n g e d t h e r e f o r e i t i s β^{-} d e c a y .
