How does the mass of a nucleus differ from the mass of an electron?
There is no simple answer.The mass of a nucleus depends on the number of neutrons and protons in the nucleus. The number of protons in the nucleus depends on the element. Moreover, the number of neutrons can vary between isotopes of the same element.
How do you convert nanograms to kilograms?
If you have some mass in nanograms, divide the number by 1,000,000,000,000 (1 trillion) to get the same mass in kilograms. 1 kilogram = 1 trillion nanograms
What is the atomic mass the weighted average of?
It's the averaged weight of all of the known isotopes of an element. Elements have versions of itself that have the same number of protons and electrons, but different number of neutrons. Since protons and neutrons have a mass of 1 amu (atomic mass unit), you change the neutron number, you change the mass . . . even though the element is still the same. Ex: Carbon 14 and Carbon 12 are isotopes of carbon. Both carbon elements, but they each have a different number of neutrons (8 vs 6), so they have different masses.
Are the same tools used to measure weight and mass?
mass is measured with a balance comparing an unknown mass with an object of known mass. weight is not measeured with the same tools as mass.
Atomic mass is equivalent to the number of?
The atomic mass is the mass of an atom of that element in AMUs. (Atomic Mass Units)The atomic number, however, is equivalent to the number of protons in an atom of that element.The mass number of an atom is the total number of protons and neutrons in the nucleus of an atom. This is therefore always a whole number. The relative atomic mass of an element is the weighted average of the masses of the isotopes relative to 1/12 of the mass of a carbon-12 atom.It is a weighted average as it takes into account the relative abundances of the different isotopes (atoms of the same element but with different numbers of neutrons) of an element. This number is found in the periodic table.For example chlorine has two isotopes, 35Cl and 37Cl, in the approximate ratio of 3 atoms of 35Cl to 1 atom of 37Cl.The number of protons and neutrons in a 35Cl atom must add up to 35, the mass number. The relative atomic mass of chlorine takes into account both isotopes and is therefore 35.5.
