But, did you ever wonder that atomic mass and molecular mass are important concepts as well? What do we do by knowing the mass of such tiny atoms and molecules? Well, the significance of these atomic and molecular masses is huge! In this chapter, we will cover the concepts and also see...
Following the discovery of electricity and the division of labor in the 1870s, machine structure and precision dramatically improved from the macro-to the micro size, enabling interchangeability and mass production. In the second half of the 20th century, the synergy of optics and light-induced ...
Atomic weight, ratio of the average mass of a chemical element’s atoms to some standard. Since 1961 the standard unit of atomic mass has been one-twelfth the mass of an atom of the isotope carbon-12. Atomic weight is measured in atomic mass units (amu),
The negative-ion mass spectra produced by kiloelectronvolt energy (CsI)nCs+ (n = 0-2) and megaelectronvolt energy 252Cf fission fragment projectile impacts on NaNO3 and NaNO2 were collected and compared. The mass spectra generated by impacts of the kiloelectronvolt polyatomic primary ions on Na...
