No, it is not correct.
The number of neutrons in an atom is easily calculated by taking the mass number and subtracting the atomic number. Take for example, Uranium: the mass number on the periodic table is 238, while the atomic number is 92. Take the difference of 238 and 92 and that will be equal to the number of neutrons. 238-92=146
To find the number of nucleons in an atom, you add the number of protons and the number of neutrons together. Nucleons are the collective term for protons and neutrons found in the nucleus of an atom.
Typically to find the number of neutrons, you first round the atomic mass to the nearest whole number. After that to you subtract the number of protons (which is the same as the atomic number) from the newly rounded atomic mass and the resulting number is the number of neutrons. lets use Carbon for example: Atomic mass: 12.01 Atomic mass rounded: 12.00 Number of Protons (same as atomic number): 6 (Rounded atomic mass - number of protons)=6 So Carbon has 6 neutrons. Hope that is easy enough to understand.
The number of protons is the same as the atomic number. For example... For the element Boron the atomic number is 5, so this would also be the number of Protons in this element. The number of electrons is the same as the number of protons. For example... For the element Boron the number of protons is 5, because that is the atomic number, so it is also thr number of electrons. This is so that the atom has an even charge between it's negative (elcectrons) and positive (protons) charges. To work out the number of neutrons you round the elements mass number to the nearest whole number. You then subtract the atomic number, from the rounded whole number, which gives you the new number of electrons. For example... For the element Boron has the mass number of 10.811. If you round that to the nearest whole number, you get 11. The atomic number of Boron is 5. You then subtract the atomic number (5) from the rounded mass number (11) which then gives you the number of neutrons found in that element. In this case if you subtract 5 from 11 toy are left with six, that is the number of nuetrons found in the element Boron. Tip- to find the atomic number and mass number, needed to find the number of protons, electrons, and neutrons, go to a site that will show you a periodic table- http://www.webelements.com/ click on the symbol of the elements name, and it will give you the mass and atomic number. Usually the mass number is located under the name and symbol, and the atomic number is usually located on top of the element's name and symbol, or in the top left hand corner.

The different isotopes have different Atomic Mass numbers, because the isotope has different numbers of neutrons. The protons and electrons are the same, so the change in mass number is the same as the change in the number of neutrons.
Take the Atomic Mass and round it to the nearest whole number. Then subtract this number and the atomic number of that element.

round the atomic weight to the nearest whole number.
To find the number of neutrons in an atom, round the mass number to the nearest whole number and subtract the atomic number.
Round this number to the nearest hundredth 0.3636 ? Round this number to the nearest hundredth 0.3636 ?
Roughly, subtract the atomic number (6) from it's atomic mass (12.01) and round to the nearest integer to get the average number of neutrons in a carbon sample, in this case 6.
Sometimes the atomic mass is listed as the average mass of the isotopes and contains a decimal. But since you can't have a fractional part of a proton or a neutron without creating a big mess, it is necessary to round to the nearest whole number. Subtracting the atomic number from the rounded atomic mass will give you the number of neutrons.
Yes, you can round your GPA to the nearest whole number.
Example: Helium: Atomic Number; 2. Atomic Mass; 4.00 The electrons are the amount of protons in the nucleus. To find the protons you subtract the atomic number by the atomic mass. If the atomic mass consists of multiple numbers, round it up to the nearest whole.
Yes, the atomic mass on the periodic table is usually rounded to the nearest whole number, so an atomic mass of 30.97 would be rounded to 31.
We don't round off atomic masses. The averaged atomic mass depends on the proportions of the various isotopes of that element. In this case, the element is hydrogen, which normally has an atomic mass of 1. Most hydrogen atoms have a single proton and no neutrons, so a total of 1. There's an isotope of hydrogen sometimes called "heavy hydrogen" or "deuterium", which has one proton (which makes it hydrogen) but which also has one neutron, for an atomic mass of 2. You can probably calculate how many "1"s you need to include for each "2" to make the average 1.0079. It's a bunch. There's an even heavier isotope called "tritium", which has one proton and two electrons, for an atomic mass of 3. Tritium is radioactive, and does not occur in nature except as a product of radioactive decay.
