Problem: Write the balanced equation for the following nuclear reactions:(b) 5626Fe + 21H → 42He + ?

FREE Expert Solution

Recall that in a nuclear reaction, the number of protons and neutrons is affected and the identity of the element changes. 


The different types of radioactive decay are:

• Alpha decay: forms an alpha particle (42α, atomic mass = 4, atomic number = 2)

• Beta decay: forms a beta particle (0–1β, atomic mass = 0, atomic number = –1). The beta particle appears in the product side.

• Gamma emission: forms a gamma particle (00γ, atomic mass = 0, atomic number = 0)

• Positron emission: forms a positron particle (01e, atomic mass = 0, atomic number = 1)

• Electron capture: the initial nuclide captures an electron (0–1e, atomic mass = 0, atomic number = –1). The electron appears in the reactant side.


The nuclear equation must be balanced with the same total atomic mass and atomic number on both sides.

Step 1: Balance the atomic mass on both sides.

Step 2: Balance the atomic number on both sides.

Step 3: Identify the missing nuclide
