1 Although the mean speed of the electron in hydrogen is only 1/137th of the speed of light, many modern experiments are sufficiently precise that a complete theoretical explanation requires a fully relativistic treatment of the problem.

The number of molecules is therefore 6.022*10 23 * 55.556 = 3.346*10 25 molecules. The number of atoms is 3 times larger because each molecule has three atoms, so there are 1.0038*10 26 atoms in a liter of water. Now we know enough to answer your question. A typical human head weighs about 10 - 12 pounds.

A) Each hydrogen atom has a partial positive charge; the nitrogen atom has a partial negative charge. B) The nitrogen atom has a strong positive charge; each hydrogen atom has a strong positive charge. C) Each hydrogen atom has a slight negative charge; the nitrogen atom has a strong positive charge.

The Rydberg constant RM for a hydrogen atom (one electron), R is given by: where M is the mass of the atomic nucleus. For hydrogen-1, the quantity is about 1/1836 (i.e. the electron-to-proton mass ratio).

The equation is fairly simple. The number of atoms of ANY substance in a volume is: # of atoms = N * (density) * volume / (Molecular Weight). N is a constant called Avogadro's number and its equal to 6.022*10 23 atoms/ mole. It can also be molecules per mole.

A hydrogen atom is an atom of the chemical element hydrogen. The electrically neutral atom contains a single positively charged proton and a single negatively charged electron bound to the nucleus by the Coulomb force. Atomic hydrogen constitutes about 75% of the elemental (baryonic) mass of the universe.

The principal quantum number in hydrogen is related to the atom's total energy. Note that the maximum value of the angular momentum quantum number is limited by the principal quantum number: it can run only up to n − 1, i.e. ℓ = 0, 1, ..., n − 1.
