Chapter 9, Problem 9.9P

Interpretation Introduction

Interpretation:

The difference between alpha particle and a proton should be determined.

Concept Introduction:

• Proton are located in the nucleus of an atom and are positively charged. The number of protons is electrically balanced by the number of electrons (which are negatively charged) in the neutral element.
• Alpha particle contains 2 neutrons and 2 protons that is helium nuclei which is ejected with high energy from an unstable nucleus to form stable atom in the radioactive decays.
