A.RAMA NAGESWARARAO · Accepted Answer

## CORE INFORMATION
✓ **Answer**: Option C
## CONCEPT FRAMEWORK
 **Primary Concept**: Beta decay
 **Related Topics**: Nuclear physics, radioactive decay, isotopes
 **Prerequisites**: Understanding of atomic number, mass number, and beta decay process.
## SOLUTION PATHWAY
**Given Information**:
  Tritium undergoes beta decay.
  Tritium is an isotope of hydrogen with 1 proton and 2 neutrons ($^3_1H$)
**Method & Steps**:
 1. Understand Beta Decay:
  Reasoning: Beta decay involves the conversion of a neutron into a proton, an electron (beta particle), and an antineutrino.  The atomic number increases by 1, while the mass number remains the same.
  Formula/Rule: $^A_ZX ightarrow ^A_{Z+1}Y + e^- + \bar{
u}_e$
 2. Apply to Tritium:
  Working: Tritium ($^3_1H$) undergoes beta decay. A neutron converts to a proton. Thus, the atomic number increases by 1 (from 1 to 2), while the mass number remains 3.
  Key Point: The product nucleus will have 2 protons and 1 neutron.
 3. Identify the Product Nucleus:
  Result: The product nucleus is Helium-3 ($^3_2He$)
  Verification: The mass number is conserved (3), and the atomic number is conserved (charge balance).
 ## OPTION ANALYSIS
[A] :x: Helium-2 ($^2_2He$): This isotope is not a product of tritium beta decay; it would imply a change in mass number.
[B] :x: Helium-4 ($^4_2He$): This isotope is not a product of tritium beta decay; it would imply a change in mass number.
[C] ✓: Helium-3 ($^3_2He$): This is the correct product nucleus, as explained above.
[D] :x: Hydrogen-2 ($^2_1H$): This is deuterium; beta decay doesn't decrease the atomic number.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing beta-plus and beta-minus decay: Remember that in beta-minus decay (like in tritium), a neutron turns into a proton.
  2.Incorrectly changing the mass number: The mass number remains constant during beta decay.
 **Quick Tips**:
  1.Focus on the change in atomic number (+1 for beta-minus decay).
  2.Remember that the mass number stays the same.
