The proton is a subatomic particle with a positive electric charge. It is a fundamental constituent of all atomic nuclei and is denoted by the symbol "p" or "p+".
Properties of Protons
Charge: The charge of a proton is approximately +1.602 x 10-19 coulombs.
Mass: The mass of a proton is approximately 1.6726 x 10-27 kilograms.
Location: Protons are located within the atomic nucleus and contribute to the mass of the atom.
Stability: Protons are considered stable particles and do not decay under normal circumstances.
Protons play a crucial role in determining the identity of an element. The number of protons in an atom's nucleus is known as the atomic number, which determines the element's place in the periodic table.
Protons are extensively used in scientific research, particularly in the field of particle physics, where they are accelerated to high speeds in particle accelerators to study their interactions with other particles.
Study Tips
Understand the concept of the atomic nucleus and the role of protons in it.
Identify and analyze forces responsible for changes in rotational motion and develop an understanding of the effect of rotational inertia on the motion of a rotating object (e.g., merry-go-round, spinning toy, spinning figure skater, stellar collapse [supernova], rapidly spinning pulsar).
