Step 1

An alpha particle is a helium nucleus, which consists of two protons and two neutrons. Therefore, its mass number is 4 (2 protons + 2 neutrons) and its atomic number is 2 (number of protons). We can represent an alpha particle in two ways. The first way is to use Show more…

Key Concepts

Proton

Protons are positively charged subatomic particles located in the nucleus of an atom. They are fundamental to defining the identity of an element and are usually denoted by the symbol p, emphasizing their role in determining the atomic number.

Alpha Particle

Alpha particles are helium nuclei comprised of two protons and two neutrons. They are key in nuclear reactions and are commonly represented by the symbol ? or by indicating the components as ??He, reflecting their origin from helium.

Beta Particle

Beta particles are electrons (or positrons) emitted during radioactive decay processes. They play a significant role in nuclear physics and are typically symbolized by the Greek letter ?, which can sometimes be accompanied by a sign to distinguish between the two types.
