Sign in Open App. A hydrogen like atom of atomic number z is in an excited state of quantum number 2n. It can emit a maximum energy photon of eV. If it makes a transition to quantum state n, a photon of energy Correct answer is ' Can you explain this answer? Verified Answer. Most Upvoted Answer. Energy Emitted during Transition When a hydrogen-like atom transitions from one quantum state to another, it emits a photon with energy equal to the difference in energy between the two states. Calculating the Energy of the Maximum Photon The given maximum energy of the emitted photon is eV. Using the formula mentioned earlier: View all answers. Have you?

A hydrogen like atom of atomic number Z is in an excited state of quantum number 2 n. It can emit a photon of maximum energy e V. If it makes a transition to quantum state n , a photon of energy The value of n will be. Byju's Answer. Open in App.

In , after returning to Copenhagen, he began publishing his theory of the simplest atom, hydrogen, based on the planetary model of the atom. For decades, many questions had been asked about atomic characteristics. From their sizes to their spectra, much was known about atoms, but little had been explained in terms of the laws of physics. As noted in "Quantization of Energy," the energies of some small systems are quantized. Maxwell and others had realized that there must be a connection between the spectrum of an atom and its structure, something like the resonant frequencies of musical instruments. But, in spite of years of efforts by many great minds, no one had a workable theory.

The model has a special place in the history of physics because it introduced an early quantum theory, which brought about new developments in scientific thought and later culminated in the development of quantum mechanics. Solar absorption lines are called Fraunhofer lines after Joseph von Fraunhofer , who accurately measured their wavelengths. During —, Gustav Kirchhoff and Robert Bunsen discovered that for the various chemical elements, the line emission spectrum of an element exactly matches its line absorption spectrum. An absorption spectrum is observed when light passes through a gas. The missing wavelengths tell us which wavelengths of the radiation are absorbed by the gas. The emission spectrum is observed when light is emitted by a gas. Positions of the emission lines tell us which wavelengths of the radiation are emitted by the gas. Each chemical element has its own characteristic emission spectrum.

The emission spectrum of hydrogen can be directly calculated from the energy level transitions. Can you explain this answer? The quest for new elements is usually described using atomic numbers. Forgot Password. The number of electrons in each element's electron shells , particularly the outermost valence shell , is the primary factor in determining its chemical bonding behavior. The correct option is D. Montgomery Questions. JEE Main Coaching. Chapter Pages. A little more than three-quarters of naturally occurring elements exist as a mixture of isotopes see monoisotopic elements , and the average isotopic mass of an isotopic mixture for an element called the relative atomic mass in a defined environment on Earth determines the element's standard atomic weight.

The hydrogen atom, consisting of an electron and a proton, is a two-particle system, and the internal motion of two particles around their center of mass is equivalent to the motion of a single particle with a reduced mass.

A hydrogen like atom of atomic number Z is in an excited state of quantum number 2 n. Select a course to view your unattempted tests.
