Potassium oxide is K2O.
It has 46 protons and 46 electrons (19 + 19 + 8 = 46).
If the most stable isotope of K and O are used (K-39 and O-16), then there will be 48 neutrons (20 + 20 + 8 = 48).
So the total number of sub atomic particles will be 140(46 protons + 46 electrons + 48 neutrons).
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".
Sodium (23Na) has 11 protons and electrons and 12 neutrons.
A Helium Nucleus so 2 protons and 2 neutrons Quarks are contained within the neutrons & protons and there are many types
Radon has 86 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a radon isotope = Mass number - 86
There are 19 protons in the potassium atom.
Potassium oxide, with the chemical formula K2O, consists of two potassium ions (K+) and one oxide ion (O2-). Therefore, there are a total of 3 ions in potassium oxide.
There are 2 elements in potassium oxide, which are potassium and oxygen.
K2O: 3 atoms in the molecule K2O2: 4 atoms in the molecule KO2: 3 atoms in the molecule
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 two: potassium and oxygen.
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
