Symbols of nucldes doesn't contain symbols of subatomic particles.
But: the atomic number is equal to the number of neutrons.
Example:
235
92U (the fissile isotope of uranium)
- 235 is the mass number (sum of protons and neutrons)
- 92 is the number of protons and electrons
The atom of a chemical element contain protons, neutrons and electrons; the number is specific for each isotope.
A nuclide symbol represents a specific isotope of an element and consists of the element's chemical symbol, atomic number, and mass number. The chemical symbol is a one- or two-letter abbreviation for an element, the atomic number is the number of protons in the nucleus, and the mass number is the sum of protons and neutrons in the nucleus.
Chlorine has 18 subatomic particles, which consist of 17 protons, 18 neutrons, and 17 electrons.
Three subatomic particles were discovered in the 1900s: the neutron in 1932, the positron in 1932, and the neutrino in 1956.
Subatomic particles with no mass are called neutrinos. Neutrinos are elementary particles that have extremely small, non-zero masses, but they are considered nearly massless in many calculations due to their very small mass values.
There are many many subatomic particles, the main three are protons, neutrons, and electrons. Go to the Related Link below, for the relevant page at Wikipedia.org, "The World's Encyclopedia".
There are 3 kinds of Sub-Atomic particles. These are Proton, Electron, Neutron.
The only subatomic particles that exist in an atom are protons, neutrons, and electrons.
more than 400
The particles outside of an atom are called electrons :D
Chlorine has 18 subatomic particles in its nucleus, which consists of 17 protons and typically 18 neutrons. Chlorine also has 17 electrons orbiting the nucleus.
Gold has 79 protons and electrons and also 118 neutrons.
