It is 13.2 grams.
The sum of any number and 0 is the original number.
let the number be n, then the sum of the number and 2 is n+2
If you add zero to any number, the sum is the same number you started with.
When the sum of a number plus 3 is squared, it is 11 more than the sum of the number plus 2 when squared.
The mass number is the sum of protons and neutrons in the atomic nucleus.
You think probably to mass number; the mass number is the sum of protons and neutrons.
The total number of subatomic particles in the nucleus of an atom consists of the sum of protons and neutrons. This is known as the atomic mass number or nucleon number.
To calculate the number of subatomic particles in isotopes, you need to know the atomic number (number of protons) and mass number (sum of protons and neutrons) of the isotope. Subtract the atomic number from the mass number to find the number of neutrons. The number of electrons will be equal to the number of protons if the atom is neutral.
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 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 that contribute to the mass of an atom are protons, neutrons, and electrons. Protons and neutrons are located in the nucleus and account for most of the mass, while electrons have negligible mass but contribute to the overall charge and stability of the atom.
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 sum of the masses of the subatomic particles in an atom's nucleus is less than the total mass of the nucleus. This is because some mass is converted into binding energy to hold the nucleus together via Einstein's mass-energy equivalence principle (E=mc^2).
Bromine-80 has 35 protons, 35 electrons, and 45 neutrons. This information is determined by the atomic number (number of protons) and mass number (sum of protons and neutrons) of the isotope.
The sum of protons and neutrons in an atom is known as the atomic mass or mass number of an element. It is typically shown as the whole number next to the element's symbol in the periodic table.
Carbon has a larger atomic mass than boron because it has more protons, neutrons, and electrons. The atomic mass of an element is the sum of the protons and neutrons in the nucleus of an atom, and carbon has more of these subatomic particles compared to boron.
