Complete the following nuclear equations by entering the missing isotope:
Margarita [4]

The nuclear equation :

₈₂²¹⁴Pb ⇒ ₈₃²¹⁴Bi + ₋₁⁰e

<h3>Further explanation </h3>

Given

₈₂²¹⁴Pb

beta β ₋₁e⁰ particles

Required

Nuclear equation

Solution

Radioactivity is the process of unstable isotopes to stable isotopes by decay, by emitting certain particles,  

  • alpha α particles ₂He⁴
  • beta β ₋₁e⁰ particles
  • gamma particles ₀γ⁰
  • positron particles ₁e⁰
  • neutron ₀n¹

The principle used is the sum of the atomic number and mass number before and after the decay reaction is the same

The reaction

₈₂²¹⁴Pb ⇒ X + ₋₁⁰e

The element X has

-the atomic number = 82 + 1 = 83

-the mass number = 214

In the periodic system, the element with atomic number 83=Bismuth
