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...
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...
1 The relative atomic mass of an element is always D A the mass of an atom of the element relative to z the mass of a carbon-12 atom. B the mass of an atom of the element relative to the mass of a hydrogen atom.☐ C the weighted mean mass of an atom of the element relativ...

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. ...
atomic mass- (chemistry) the mass of an atom of a chemical element expressed in atomic mass units atomic weight,relative atomic mass mass- the property of a body that causes it to have weight in a gravitational field combining weight,eq,equivalent weight,equivalent- the atomic weight of an ...
The atomic mass of an element is the total mass of its protons, neutrons, and electrons. On the Periodic Table of Elements, the atomic number of an element is equivalent to its number of protons.Answer and Explanation: The average atomic mass of hydrogen is 1.008. The average atomic mass ...
equal to 1/12 of the atomic mass of the most abundant isotope of a carbon atom in its lowest energy state, defined as 12 Da. Although the termatomic mass unit(amu) has been regarded as equivalent to the Da, it is only approximately equal to the dalton and now is considered an obsolet...
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...
