Symbols of subatomic atoms

The symbols used to represent subatomic particles in atoms are as follows:

1. Proton: The symbol for a proton is "p+". It represents a positively charged particle found in the nucleus of an atom.

2. Neutron: The symbol for a neutron is "n". It represents a neutral or uncharged particle found in the nucleus of an atom.

3. Electron: The symbol for an electron is "e-". It represents a negatively charged particle orbiting the nucleus of an atom.

These symbols, along with the atomic number and mass number, are used to represent the composition of an atom in atomic notation. For example, the atomic notation for helium is He^4, where "He" represents the element helium, and the superscript "4" represents the mass number.
