What is the mass of a single hydrogen atom?Number of molesThe number of moles can be defined as the ratio of the given mass to the atomic mass, or it can be the ratio of the number of the particles to the Avogadro number.Answer and Explanation: ...
1CHEMISTRY-RELATIVE ATOMIC MASSthe 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角度...
100分求一道物理题 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?

iThe energy of the photon is not enough to excite the electron to energy #Thus the electron remain in its ground state and photon is not absorbed fifty-three photon remain unchanged [B1]iiThe energy of the photon is enough to ionise the atom ÷ to remove the electron from the atom. @...
The path integral for the Green's function involving the Coulomb potential in combination with the Kustaanheimo-Stiefel transformation is used to generate the atomic orbitals of the nonrelativistic hydrogen atom as various combinations of the product of one-dimensional isotropic harmonic oscillator wave ...
