Understanding the structure of atoms was crucial for comprehending the fundamental properties of matter and the behavior of chemical elements.
Protons were thought to be located in the interior of the atom because electrons could be easily removed from atoms, whereas protons seemed to remain bound within the atom.
Scientists observed that atoms exhibited both positive and negative charges, leading them to infer the presence of positively charged protons and negatively charged electrons within atoms.
The mass of an electron is considered negligible, and its charge is minus one (-1).
