No, electrons are not quarks. Quarks and electrons are both elementary particles, but they belong to different categories and have different properties.
Quarks are fundamental particles that are affected by the strong nuclear force, also known as the strong interaction. Quarks come in six different types, or flavors, known as up, down, charm, strange, top, and bottom. Protons and neutrons, which are the building blocks of atomic nuclei, are made up of combinations of quarks.
On the other hand, electrons are elementary particles known as leptons. Leptons do not experience the strong nuclear force but are instead influenced by the electromagnetic force. Electrons are negatively charged particles and are found in orbit around atomic nuclei. They play a crucial role in determining the chemical and electrical properties of matter.
So, in summary, quarks and electrons are distinct types of elementary particles with different properties and interactions.
