That depends entirely on which element it is. for instance, the nucleus of a helium atom would weigh more than the nucleus of a hydrogen atom.
Protons and neutrons make up the atomic weight of an atom. Protons have a positive charge and are found in the nucleus, while neutrons have no charge and are also located in the nucleus. The total number of protons and neutrons determines the atomic weight of an atom.
Neutrons and protons combined
Atomic weight/ mass = number of protons + number of neutrons
Most atomic of iodine has 74 neutrons. The atomic weight of iodine (126.9) represents the combined mass of protons, neutrons, and electrons in the atom. Since the atomic number (53) represents the number of protons in the nucleus, subtracting the atomic number from the atomic weight gives the number of neutrons.
The atomic number of an element is determined by the number of protons in the nucleus, which can be identified through methods like spectroscopy and X-ray diffraction. Atomic mass is determined by the total number of protons and neutrons in the nucleus, which can be calculated based on the element's isotopic composition and their respective masses.
To find the number of neutrons, all you need to do is round the atomic weight to the nearest whole number. The atomic weight of nitrogen is 14.007, or about 14. The atomic weight is basically the average number of particles in an atom's nucleus. What particles are located in the nucleus?? The protons and the neutrons. So, all you have to do is subtract the number of protons from the atomic weight and you get the neutrons!!HERE'S HOW YOU DO IT:Nitrogen's atomic # = 7Nitrogen's atomic mass = 14Neutrons + Protons = Atomic Mass so... 14-7=7The number of neutrons is 7.
The "Atomic number" of an element corresponds to the number of only the protons in the nucleus of its atoms. Add to that the number of neutrons that are also in there, and you have the "Atomic weight".
Atoms are composed of particles called nucleons. There are 2 types of nucleons. They are the positively charged proton and the neutral (no charge) neutrons. There are also negatively charged particles called electrons that orbit the nucleus.
Protons and neutrons make up the atomic weight of an atom. Protons have a positive charge and are found in the nucleus, while neutrons have no charge and are also located in the nucleus. The total number of protons and neutrons determines the atomic weight of an atom.
The atomic weight of a compound is the number of protons and neutrons in the atom's nucleus (since they both have an atomic weight of 1).
Atoms contain three different sub-atomic particles. Protons, which are particles with a positive charge, and neutrons, particles with a neutral charge are found in the nucleus at the center of the atom. Surrounding the nucleus are electrons, particles that have negative charge.
The sub-atomic weight of 1 ounce of cheese would be the combined weight of all the sub-atomic particles (protons, neutrons, and electrons) that make up the atoms in the cheese. This weight would be extremely small and not typically measured or relevant in everyday situations.
On the Periodic Table, there are two numbers for every element: the atomic number and the atomic weight. The numbers at the top of the square represents the number of protons present in the atom's nucleus of that element. This is called the atomic number. For example, the atomic number for the element Krypton is 36. That means that there are 36 protons in the nucleus. If there were not 36 protons in the nucleus of that atom, that would create the atom of a completely different element. For example, if one proton was to be removed from the nucleus of the atom for the element of Krypton that atom will be an atom of the element bromine. The number at the bottom of the square represents the number of particles present in the atom's nucleus of that element. This is known as the atomic weight. For example, the atomic weight for the element Krypton is 83.80.

The question isn't even spelled correctly. Dont you mean "cast"? Regardless, atomic weight refers to the combined number of protons & neutrons in the nucleus of an atom. Light is not an atom. It is a photon (particle) or an electromagnetic wave. It has no mass & no atomic weight. Light does not cast a shadow. The shadow is cast by an object blocking the light.
