# A proton has enough mass energy to decay into a shower madeup of electrons, neutrinos, and their antiparticles. Which of the followingconservation laws would necessarily be violated if it did: electron lepton number or baryon number?

The Baryon number will be violated.

See the step by step solution

## Step 1: Concept used to solve the question.

• Conservation of lepton number:

In all particle interactions, the net lepton number is conserved.

• Conservation of baryon number:

In all particle interactions, the net baryon number is conserved.

## Step 2: Finding which conservation law would be violated

As we know, the electron lepton number of protons is zero. If there is an equal number of electrons and their anti-particles, the lepton number could be zero.

And the Baryon number of the proton is one and of other particles zero. Therefore Baryon number will be violated.
