3 CHEMISTRY-RELATIVE ATOMIC MASS the mass of a hydrogen atom 1/1H is equal to 1/12 of the mass of a carbon-12 atom, so its relative isotopic mass is 1.A magnesium atom 24/12Mg is twice as heavy as a carbon-12 atom,so its relative isotopic mass is 24 再给另一个例子 不要用英文...
If the mass of a hydrogen atom is 1.67*10^-27kg and the mass of an electron is 9.1*10^-31kg,how many electrons would be required to have a mass equivalent to one hydrogen atom? 下载作业帮APP学习辅导没烦恼 答案解析 结果1 举报 这道题的意思是一个氢原子的质量是1.67*10^-27kg ,一个...
The mass of one atom ofhydrogen-1 = 1.007 AMU The mass of one atom of titin (the largest known protein) = 3 x 106AMU Each12C atom has six protons and six neutrons in its nucleus, adding up to an atomic mass of 12 AMU.Electronshave a low mass, so they are assumed to have a ne...

Re: Mass of a line of hydrogen atoms « Reply #5 on: April 29, 2019, 08:03:10 AM » As a side note, the radius of an atom is very ill-defined. Atoms themselves are fuzzy, and the distance between the nuclei depends on what nuclei, what bond, and pretty much everything. ...
Using a mass spectrometer, physicists have determined the mass of a hydrogen atom to be 1.660538921(73) × 10-27 kilograms, where the parenthetical digits are not known with complete certainty. That's accurate enough for most purposes. Good vibrations Another way that the mass of an atom can...
The mass of a neutron is 1.008 665 u while that of the hydrogen atom is 1.007 825 u. Since both neutrons and protons have almost unit atomic masses, the atomic mass of a nuclide should be close to the number of nucleons, i.e. the mass number. However, when the table of elements ...
