00:00:00 - 00:00:00

This video covers the basics of subatomic particles, including their definitions, where they are located within an atom, and their functions. This information is important for understanding the role these particles play in the formation of chemical bonds and in providing mass to atoms.

• 00:00:00 In this video, we'll review the properties of subatomic particles, starting with the definition of an atom according to the atomic theory of Dalton. An atom is defined as the basic unit of an element that participates in chemical reactions, and is incredibly small and indivisible. However, it was demonstrated in the early 20th century that atoms are composed of smaller particles known as subatomic particles. These are the proton and neutron. We'll review some of their characteristics, starting with the way that the proton is represented with a small p minuscule with a positive power, and the neutron is represented as n with an exponents 0. We'll also review where these particles are located within an atom's nucleus. The proton and neutron are located within the atom's nucleus, while the electron is located around the nucleus in circular orbits. The first subatomic particle that was discovered was the electron, which was discovered by Joseph John Sampson in 1897. Ernest Rutherford and James Chadwick later discovered the proton. The functions that subatomic particles play are especially important in the case of the electron, as they are responsible for forming chemical bonds and providing mass to the atom. Lastly, subatomic particles are important because they are responsible for moving around the
