To determine properties of matter.Study of sub particles is essential.
Electrons are one of the things that make up an atom. So an electron is smaller.
Things are made up of atom. Atoms are small particles.
An atom is smaller.
There are a few substances smaller than the atom, they're called sub-atomic particles and include things like protons, neutrons, electrons, photons, quarks etc.
The neutron is a part of the atom, therefore it is smaller.
The Universe was never smaller than an atom.
Thomson's discovery of the electron showed that there were things smaller than the atom that could be removed from the atom. Therefor the atom was not an "uncuttable" object as Dalton had proposed.
smaller
An atom is smaller than a compound because if an electron fits in an atom, and an atom is a part of a compound, it means a compound is bigger than an atom
Protons and neutrons cannot be directly observed within the nucleus due to their small size. Physicists study their motion and behavior indirectly using techniques like scattering experiments, particle accelerators, and nuclear reactions. These methods provide insights into the structure and properties of the nucleus.
Atomic physicists do not fully understand why all atomic particles stay together within an atom because the forces that hold them together, such as the strong nuclear force, are complex and not yet fully understood.
an atom is about a trillion times smaller then a speck of dust.
