Which among alpha and beta particles have higher ionising power and why?

Explanation

To determine which among alpha and beta particles has higher ionizing power, we can follow these steps:

### Step 1: Define Alpha and Beta Particles
- **Alpha Particle**: An alpha particle is essentially a helium nucleus, consisting of 2 protons and 2 neutrons. Its mass is approximately 4 atomic mass units (4U).
- **Beta Particle**: A beta particle is either an electron (β-) or a positron (β+). Both have a very small mass of about 0.0005 atomic mass units (or 1/2000 U).

### Step 2: Understand Ionizing Power
- **Ionizing Power**: Ionizing power refers to the ability of a particle to ionize atoms, which means knocking electrons out of atoms. The more ionization that occurs, the higher the ionizing power of the particle.
