In this case, the number 209 represents the sum of protons + neutrons.
There Are Three Sub atomic particles-Electron,proton and neutron

The chemical element, bismuth, has an atomic number of 83. That means that, assuming it's electrically neutral, it has 83 protons and 83 electrons. Since we know that this particular isotope of bismuth has a combined total of 205 protons and neutrons, the total number of subatomic particles in 205Bi; i.e., the total number of protons, neutrons, and electrons, is 205 + 83 = 288.
protons and neutrons are found in the nucleus of all atoms. Phosphorus always has a total of 15 protons so if it is 32P then the number of neutrons must be 17because 32 is the total mass of the atom.
The answer depends on the atom! The total number of subatomic particles in an atom of an isotope is the sum of the mass number and the atomic number of the isotope; the mass number counts the protons and neutrons together, and the atomic number recounts the number of protons, which in a neutral atom must be the same as the number of protons.
The "subatomic" particles in atoms are usually considered to be only protons, neutrons, and electrons, although these may contain sub-subatomic particles such as quarks and gluons. Every atom of xenon contains 54 protons and 54 electrons, because 54 is the atomic number of xenon. Every atom of xenon also contains neutrons. The lightest naturally occurring and radioactively stable isotope of xenon is Xe-124. Since the mass number is the sum of protons and neutrons, the total of protons, electrons, and neutrons for this isotope is 124 + 54 or 178. The number of particles for any other isotope of xenon may be found by adding the mass number to the atomic number.
The total number of subatomic particles in the nucleus
False; the atomic number is the total number if protons in the nucleus only.

There are two types of particles in the nucleus of an atom, which are the Protons and the Neutrons. The number of particles in the nucleus depends what is the element. For example, Oxygen has 8 protons and 8 neutrons in the nucleus and Phosphorus has 15 protons and 16 neutrons in the nucleus.

Protons and neutrons. The amu of an atom is the total number of protons and neutrons added together.

In chemistry and physics, a nucleon is one of the two particles that make up the atomic nucleus. Protons are one of the nucleons, Neutrons are the other nucleon.Thus by subtracting the number of Protons in the nucleus (the Proton number) from the total number of nucleons (the nucleon number) you will get the total number of Neutrons (the neutron number) in the atoms nucleus.
The Wikipedia lists an estimate of 10 to the power 80 hydrogen atoms for the observable Universe. The total number of particles would be somewhere in that order, depending on what "particles" you are thinking of.
