Hydrogen atom: h2 2 r2 d dr r2 dR(r) dr + " h2l(l+1) 2 r2 V(r) E # R(r) = 0 The solutions of the radial equation are the Hydrogen atom radial wave-functions, R(r). II. Solutions and Energies The general solutions of the radial equation are products of an exponential and a polynomial. The eigenvalues (energies) are: E= Z2e2 8ˇ oaon2 = Z e4 8 2h2n2 n= 1;2;3;:: The hydrogen atom is the simplest atom in nature and, therefore, a good starting point to study atoms and atomic structure. The hydrogen atom consists of a single negatively charged electron that moves about a positively charged proton (). In Bohr’s model, the electron is pulled around the proton in a perfectly circular orbit by an attractive Coulomb force. The light emitted by hydrogen atoms is red because, of its four characteristic lines, the most intense line in its spectrum is in the red portion of the visible spectrum, at 656 nm. With sodium, however, we observe a yellow color because the most intense lines in its spectrum are in the yellow portion of the spectrum, at about 589 nm.

Hydrogen Properties. The hydrogen atom consists of a nucleus, formed of a single proton, and of a single electron. The hydrogen molecule consists of two hydrogen atoms bounded together. The molar mass of hydrogen is 2.016 g/mole.

Although the energy of an electron in a hydrogen atom can be specified by giving the quantum number n, the motion of an electron moving in three dimensions is not completely specified by giving the value of its energy. The ground state energy level of the electron in a hydrogen atom is −13.6 eV, which is equivalent to an ultraviolet photon of roughly 91 nm wavelength..

Now, it is conventional to refer to the energy eigenstates of a hydrogen atom which are also simultaneous eigenstates of as states, where is the radial quantum number, as , and is the total angular momentum quantum number.

Hydrogen only has 1 electron which can't travel up each spectral line. There are thousands of hydrogen atoms so together they can let off or group up to form all four colors. The hydrogen atom may have other energies that are higher than the ground state. These higher energy states are known as excited energy states of a hydrogen atom. There is only one ground state, but there are infinitely many excited states because there are infinitely many values of n in Equation 6.45.

hydrogen atom - Swedish translation – Linguee

What is the energy of the electron The simplest classical model of the hydrogen atom is one in which the electron moves in a circular planar orbit about the nucleus as previously discussed and as illustrated in Figure 3-7. The angular momentum vector M in this figure is shown at an angle q with respect to some arbitrary axis in space. Hydrogen is the only element whose isotopes have been given different names. Deuterium and Tritium are both used as fuel in nuclear fusion reactors. One atom of Deuterium is found in about 6000 ordinary hydrogen atoms. Deuterium is used as a moderator to slow down neutrons.

Hydrogen AtomAtom is a 3D object, and the electron motion is three-dimensional. We’ll start with the simplest case j, p- a hydrogen atom. An electron and a proton (nucleus) are bound by the central-symmetric Coulombinteraction.

The hydrogen atom consists of a single negatively charged electron that moves about a positively charged proton (Figure \(\PageIndex{1}\)).
