Solution: Rank alpha particles, beta particles, positrons, and gamma rays in terms of increasing penetrating power.

Solution: Rank alpha particles, beta particles, positrons, and gamma rays in terms of increasing penetrating power.

Problem

Rank alpha particles, beta particles, positrons, and gamma rays in terms of increasing penetrating power.

Solution

We’re being asked to determine which particle has the most penetrating power rank 


The different types of particles are:

alpha particle:  42α (atomic mass = 4, atomic number = 2, positively charged)

beta particle:  0–1β (atomic mass = 0, atomic number = –1, negatively charged)

gamma particle:  00γ (atomic mass = 0, atomic number = 0, no charge)

positron particle:  01e (atomic mass = 0, atomic number = 1, positively charged)

neutron: 10n (atomic mass = 1, atomic number = 0, neutral)
