Are you looking for an answer to the topic “How can there be multiple lines if hydrogen only has one electron?“? We answer all your questions at the website Chiangmaiplaces.net in category: +100 Marketing Blog Post Topics & Ideas. You will find the answer right below.
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.1 Answer. when a hydrogen atom, having different energy levels absorbs energy the only electron can go any of the energy levels & while radiating different spectral lines observed.1 Expert Answer. The key word here is “visible.” The human eye is only sensitive to light with wavelength between about 400 and 700 nm. If you calculate the emission spectrum of hydrogen, you will find that only four emission lines have wavelengths in this range.

How can a hydrogen atom which has only one electron?
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.
How many lines are possible in the emission spectrum of hydrogen?
So, there are four lines in the visible spectrum of hydrogen.
Why a single atom of hydrogen Cannot produce all four hydrogen spectral lines?
Explain why a single atom of hydrogen cannot produce all four hydrogen spectral lines simultaneously. A single hydrogen atom only has one electron so it can’t have all four transitions at the same time.
How many spectral lines are seen for hydrogen atom when electron jumps from?
Answer: Spectral lines in visible region will be 3.
Why is the emission spectrum of hydrogen not continuous?
Hence, atomic emission spectra represent the electrons returning to lower energy levels. Each packet of energy corresponds to a line in the atomic spectrum. There is nothing between each line, so the spectrum is discontinuous.

How can we see all 4 colors from a hydrogen gas discharge tube?
In a hydrogen gas discharge tube, there are millions of hydrogen atoms filling the tube. Each one can have a different transition occurring, so all of the colors are represented by some fraction of the atoms present.
What is wrong about emission spectrum of hydrogen?
Answer. Answer: The number of lines does not equal the number of electrons in an atom.
How does Bohr model explain the line spectrum of hydrogen?
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.
How can elements with low atomic numbers have so many spectral lines?
How can elements with low atomic numbers have so many spectral lines? Spectral lines are formulated when electrons make transitions between their own energy levels. When an electron is excited it doesn’t stay in its lowest state it jumps to a different state to make up for the extra energy.
What do the lines in the hydrogen spectrum represent?
Each thin band in each spectrum corresponds to a single, unique transition between energy levels in an atom.

How are spectral lines produced?
Spectral lines are produced by transitions of electrons within atoms or ions. As the electrons move closer to or farther from the nucleus of an atom (or of an ion), energy in the form of light (or other radiation) is emitted or absorbed.…
How do you find the number of spectral lines?
For example, suppose one atom with an electron at energy level 7 (n2=7). That electron can “de-excite” from n2=7 to n1=6,5,4,3,2, or 1. All those transitions give one spectral line for each. Thus, total of 1×6=n1(n2−n1) (foot note 1) spectral lines would be present in the spectrum.
How many spectral lines are produced in the spectrum of hydrogen atom from 5th energy level?
Hence there are 10 transitions and hence 10 spectral lines possible.

How are spectral lines like fingerprints?
A spectral line is like a fingerprint that can be used to identify the atoms, elements or molecules present in a star, galaxy or cloud of interstellar gas. If we separate the incoming light from a celestial source using a prism, we will often see a spectrum of colours crossed with discrete lines.
How many spectral lines are emitted by atomic hydrogen excited to nth energy level?
Here n2=n and n1=1. Was this answer helpful?
What happens to the hydrogen atom after the electron transition has occurred?
The hydrogen atom is a single electron atom. 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.
How many spectral lines due to electron transition will belong to Balmer series?
The series of visible lines in the hydrogen atom spectrum is called the Balmer series. This series of spectral emission lines occur when the electron transitions from a high-energy level to the lower energy level of n=2. Hence, the correct answer is Option (A) 5 lines.
Is the spectrum of hydrogen continuous or line?
Effect of the source on the continuous spectrum of hydrogen—The continuous spectrum of hydrogen is observed to be of similar character, although of differing intensity, in a number of sources, a Wood tube, an ordinary discharge tube, the separate striations of the positive column, the condensed spark in hydrogen at …

Why is it impossible to get a continuous spectrum?
As far as we know, no object in the universe sends out waves across the whole of the electromagnetic spectrum, so finding a continuous spectrum spanning the whole of the electromagnetic spectrum would be impossible.
Why does hydrogen atoms only produce light of specific frequencies?
The fact that hydrogen atoms emit or absorb radiation at a limited number of frequencies implies that these atoms can only absorb radiation with certain energies. This suggests that there are only a limited number of energy levels within the hydrogen atom. These energy levels are countable.
