A nuclear equation is balanced when

 A nuclear equation is said to be balanced if and only if the total mass number on the left hand side of the equation is equal to the total mass number on the right hand side of the equation, and if and only if the total nuclear charge on the left hand side of the equation is equal to the total nuclear charge on the right and side of the equation,

 The term nuclear charge refers to the atomic numbers or number of protons of each participating atom and the left and side refer to the reactant side while the right hand side refer to the product side in the equation

1.               ²³₁₂Mg → ²³ ₁₁Na + ⁰₁e  + v⁰₀.

2.               ¹²₆C → ¹² ₅B + ⁰₁e  + ⁰₀.

how to balance nuclear equations

Examining  the above equations we can balanced the  first equations as follows

 Total mass = total mass on the left hand side = mass number of magnesium and  is 23  

Total mass on the right hand side  = mass of sodium + mass of positron plus mass of electron neutrino = 23 +0+0= 23

  Let us balance the nuclear charge,  total charge on the left hand side which is the atomic number of magnesium= 14 and total nuclear charge on the right hand side is  11 + 1+0 =12

 Therefore both atomic mass and charge are equal from the both side , hence we can say a nuclear equation is balanced when the above conditions are satisfied

 For the second equation

 The mass on the left  right hand side is 12  and on the right hand side is  12+0+0= 12.

 The total nuclear charge on the left hand side is 6 and on the right hand side is 5+1+0= 6.
