thus giving rise to what is known asvelocity focusing. Aston’s design was the basis of his later instruments with which he systematically and accurately measured the masses of the isotopes of many of the elements. He chose16O (the isotope of oxygen of mass 16) as his standard of mass. ...
define a more convenient unit. This is the unified mass unit u and is defined on the basis that the mass of the carbon nuclide C-12 is exactly 12 u [the unified mass unit supersedes the previous unit ofatomic mass unitbased on the mass of oxygen 0-16 being 16 amu]. From this ...
OXYGEN GAS的MOLECULE就是由两粒OXYGEN ATOM组成 所以OXYGEN GAS的RELATIVE MOLECULAR MASS就是16.0X2 即是32.0... 1 MOLE的SODIUM CHLORIDE的质量就用FORMULAR MASS来表达 因为SODIUM CHLORIDE是GIANT IONIC STRUCTURE 所以1 MOLE的SODIUM CHLORIDE的FORMULAR MASS就是23.0+35.5 就是58.5gmol^-1......
The atomic motion of oxygen in a c-axis-oriented ${\\mathrm{YBa}}_{2}$${\\mathrm{Cu}}_{3}$${\\mathrm{O}}_{7\\mathrm{\\ensuremath{-}}\\mathrm{\\ensuremath{\\delta}}}$ film was studied with implanted $^{18}\\mathrm{O}$ as a tracer. Conventional annealing in an oxygen ...
Given the high amount of oxygen in the system, O2+• will also be associating with O2 to form O4+•, and then a substitution reaction with water can lead to O2+•(H2O) + O2, i.e., O4+• will also be lost through deionization, which ultimately leads to the production of ...

Pinus massoniana (Massion’s pine), a pioneer tree species, exhibits restoration potential in polluted mining areas. However, the physiological and molecular mechanisms of ectomycorrhizal (ECM) fungi in Massion’s pine adaptability to multiple-toxic-metal stress are still unclear. Hence, Massion’s...
No matter what its physical state, water (H2O) is the same compound, with each molecule composed of two atoms of hydrogen and one atom of oxygen. However, if water, as ice, liquid, or vapour, encounters sodium metal (Na), the atoms will be redistributed to give the new substances ...
