: Modern theory posits that matter is composed of these discrete units, as established by pioneers like John Dalton , who proposed that atoms combine in fixed ratios to form compounds. Scientific Reporting and Application

: Neutral particles (no charge) also found in the nucleus.

: In a neutral atom , the number of protons equals the number of electrons. If there is an imbalance, the atom becomes an ion .

The core components of any atom determine its identity, mass, and charge. : Positively charged ( +1positive 1 ) particles located in the nucleus .

: Protons and neutrons together make up the mass number (

: The number of protons is the atomic number (
