Is matter continuous and therefore has no finer structure or is it discontinuous and thus made or tiny particles
Marta_Voda [28]

Matter is discontinuous, and it is made of tiny particles called atoms

Explanation:

Matter is not a continuous structure, but it consists of tiny particles called atoms.

An atom consists of three types of particles:

  • Proton: the proton is in the nucleus of the atom. it has a positive electric charge of +1.6\cdot 10^{-19}C (also called fundamental charge). Its mass is 1.67\cdot 10^{-27}kg.
  • Neutron: the neutron is also in the nucleus of the atom, but it has no electric charge. Its mass is similar to the mass of the proton (slightly heavier). Neutrons and protons are held together in the nucleus through the strong nuclear force.
  • Electron: electrons are found in a "cloud" outside the nucleus. Electron has negative electric charge equal to -1.6\cdot 10^{-19}C. Its mass is much approximately 1800 times smaller than that of the proton, so it is considered as negligible.
