What is electrons and protons in physics?

In physics, electrons and protons are subatomic particles that make up atoms.

Electrons are negatively charged particles that orbit the nucleus of an atom. They are much smaller and lighter than protons and neutrons, and they play a key role in chemical reactions and electricity.

Protons are positively charged particles that are found in the nucleus of an atom. They are about 1,836 times heavier than electrons and are responsible for the positive charge of the nucleus. Protons also play a crucial role in determining the identity of an element, as the number of protons in an atom's nucleus determines its atomic number.

Electrons:

- Negatively charged subatomic particles
- Found in electron clouds surrounding the nucleus of an atom
- Have a mass of approximately 1/1836 of a proton
- Responsible for chemical bonds and electrical conductivity

Protons:

- Positively charged subatomic particles
- Found in the nucleus of an atom, along with neutrons
- Have a mass of approximately 1 atomic mass unit (amu)
- Responsible for the positive charge of the nucleus and the identity of the element
