let us put
down the equation fast
2714Si→2713Al
+ X
In the above reaction, the atomic mass remain unchained this signifies a
beta emission or positron emission while the nuclear charges decreases by one ,
this signifies a beta plus a positron emission, therefore the above equation
should be written as
2714Si→2713Al
+ 0+1e
That when silicon-27 emits a positron, alluminium-27
is formed.
Let us balance the equation to check if we are
wrong,
The law of conservation of matter in nuclear
reaction requires that the total mass on the product side must be equal to the
total mass on the reactant side and the
toal charge on the reactant side must be equal to the total charge on
the product side
Therefore
Total mass on the left hand side is 27 and total mass
on the right hand side is 27 +0= 27
Total charge
on the left hand side is 14 and likewise the total charge on the reactant side
is 13+1= 14
Therefore te
equation is balanced and we are not wrong
