Barium has 56 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a barium isotope = Mass number - 56
The only subatomic particles that exist in an atom are protons, neutrons, and electrons.
There are 3 kinds of Sub-Atomic particles. These are Proton, Electron, Neutron.
Of the hundreds of subatomic particles, many have an electric charge. The best-know particle with a positive charge is the proton. Subatomic particles are considered only protons, neutrons, electrons. The other particles form the large group of elementary particles (which includes also p, n and e).
Each isotope of an element has a different number of neutrons.Number of neutrons = Atomic mass of the isotope - Atomic number of the elementThe atomic number of barium is 56.For a list of barium isotopes see the link below.The answer it wants is 81.

The only subatomic particles that exist in an atom are protons, neutrons, and electrons.
Silicon has 14 protons and 14, 15 or 16 neutrons in the stable isotopes found in nature. These are located inside the nucleus.
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".

The particles outside of an atom are called electrons :D
The typical amount of particles in the nucleus of an iron atom is 56, in the isotope 56Fe which in nature is about 91.7% of iron atoms. 54Fe (5.8%), 57Fe(2.2%) and 58Fe(.28%) making up the balance.
Like all other atoms it contains three subatomic particles, they are Protons, Neutrons and Electrons.

The mass number is the sum of protons and electrons in the atomic nucleus of an isotope. Barium has many isotopes and each has another mass number.
Of the hundreds of subatomic particles, many have an electric charge. The best-know particle with a positive charge is the proton. Subatomic particles are considered only protons, neutrons, electrons. The other particles form the large group of elementary particles (which includes also p, n and e).
