Interpretation:
The mass of the electron is to be expressed as a percentage of the mass of a hydrogen atom. The percentage of the mass of hydrogen contributed by subatomic particles other than electron is to be stated.
Concept introduction:
The Dalton’s atomic theory states that an atom of an element is an indivisible particle. This theory denies about presence of any subatomic particle. The advances in science and technology pave the way to the discovery of three subatomic particles: electron, proton and neutron. The mass of an electron is found to be

- The following 'H NMR spectrum was taken with a 750 MHz spectrometer: 1.0 0.5 0.0 10.0 9.0 8.0 7.0 6.0 5.0 4.0 3.0 ' 2.0 1.0 0.0 (ppm) What is the difference Av in the frequency of RF ac Δν ac radiation absorbed by the a and c protons? (Note: it's not equal to the difference in chemical shifts.) Round your answer to 2 significant digits, and be sure it has an appropriate unit symbol. = O O a will shift left, c will shift right. O a will shift right, c will shift left. a and c will both shift left, with more space between them. Suppose a new spectrum is taken with a 500 MHz spectrometer. What will be true about this new spectrum? O a and c will both shift left, with less space between them. O a and c will both shift right, with more space between them. O a and c will both shift right, with less space between them. Which protons have the largest energy gap between spin up and spin down states?
