How can a hydrogen atom which has only one electron have so many spectral lines?
Though a hydrogen atom has only one electron, it contains a large number of shells, so when this single electron jumps from one shell to another, a photon is emitted, and the energy difference of the shells causes different wavelengths to be released… hence, mono-electronic hydrogen has many spectral lines.
How does the Bohr model of the hydrogen atom explain the hydrogen emission spectrum?
Bohr’s model explains the spectral lines of the hydrogen atomic emission spectrum. While the electron of the atom remains in the ground state, its energy is unchanged. When the atom absorbs one or more quanta of energy, the electron moves from the ground state orbit to an excited state orbit that is further away.
Why does hydrogen only have one shell?
If Hydrogen has 1 electron it can only have 1 outer shell (or orbital) as an electron cannot by split across shells. In general, the first shell can hold 2 electrons, the second can hold 8. Consequently, hydrogen only has 1 outer shell as it has less than 2 electrons so it does not need another shell.
How do electrons move within their shells?
In order to move between shells, an electron must absorb or release an amount of energy corresponding exactly to the difference in energy between the shells.
How do electrons move from atom to atom?
The very small particles can stream through wires and circuits, creating currents of electricity. The electrons move from negatively charged parts to positively charged ones. The electrons then jump from one area to another. When the electrons move, the current can flow through the system.
How can a hydrogen atom which has only one electron create so many spectral lines quizlet?
How can a hydrogen atom, which has only one electron, have so many spectral lines? The many spectral lines from the element hydrogen are the result of the many energy states the single electron can occupy when excited.
Does hydrogen only have one energy level?
If it is in the second energy level, it must have -3.4 eV of energy. An electron in a hydrogen atom cannot have -9 eV, -8 eV or any other value in between….Exercise 3.
| Energy Level | Energy |
|---|---|
| 1 | -54.4 eV |
| 2 | -13.6 eV |
| 3 | -6.04 eV |
| 4 | -3.4 eV |
What happens when an electron in a hydrogen atom moves from the excited state to the ground state?
When an atom changes from the excited state to the ground state, the electron has moved from a high energy state to a low energy state. When this occurs, the excess energy is released as light energy. This explains why atoms emit light when they change from an excited state back to the ground state.
Which one of the transition of an electron in hydrogen atom emits radiation of lowest wavelength?
Answer: The transition n2 = ∞ to n1 = 2 emits radiation of the lowest wavelength. This transition corresponds to maximum energy of emitted radiation. It is equal to the ionization energy and corresponds to the energy required when an electron is completely removed from ground state of hydrogen atom.
Does hydrogen only have one electron shell?
So… for the element of HYDROGEN, you already know that the atomic number tells you the number of electrons. That means there is only one electron in a normal hydrogen atom. iLooking at the picture, you can see there is only one electron in shell one.
Why does hydrogen only have one neutron?
The strong nuclear force between 2 protons is not enough to overcome this; neutrons contribute to the strong nuclear force without adding to the electromagnetic repulsion, thereby holding the nucleons together. Hydrogen has only 1 proton, so there is no need of a neutron, there is nothing to hold together.
What is the orbit of an electron in a hydrogen atom?
The electron in a hydrogen atom travels around the nucleus in a circular orbit. The energy of the electron in an orbit is proportional to its distance from the nucleus. The further the electron is from the nucleus, the more energy it has.
How many shells does hydrogen have in H-Spectrum?
Hydrogen has only one shell, how do electrons move from higher to orbit in h-spectrum? – Quora Something went wrong. Wait a moment and try again.
How many electrons does a hydrogen atom have?
It has one electron attached to the nucleus. The energy in a hydrogen atom depends on the energy of the electron. When the electron changes levels, it decreases energy and the atom emits photons. The photon is emitted with the electron moving from a higher energy level to a lower energy level.
What is the Bohr model of electron transition in hydrogen?
The Bohr model for an electron transition in hydrogen between quantized energy levels with different quantum numbers n yields a photon by emission with quantum energy: This is often expressed in terms of the inverse wavelength or “wave number” as follows:
