Which one of the following sets of quantum numbers represents an electron with the highest energy?
Hence, the set c of quantum numbers (n=4,l=2,m=1,s=+1/2) represents the highest energy of an atom.
Which one of the following sets of quantum numbers is not possible?
The set of quantum numbers n=1,l=1,ml=0,ms=+21 is not possible for an electron.
Which quantum number is sufficient to determine the energy of electron in hydrogen atom?
principal quantum numberSince the motion of the electron occurs in three dimensions we might correctly anticipate three quantum numbers for the hydrogen atom. But the energy depends only on the quantum number n and for this reason it is called the principal quantum number.
How are electrons described in the quantum mechanical model?
In the quantum-mechanical model of an atom, electrons in the same atom that have the same principal quantum number (n) or principal energy level are said to occupy an electron shell of the atom. Orbitals define regions in space where you are likely to find electrons.Sep 23, 2021
Which one of the following sets of quantum numbers is possible?
So correct set of quantum numbers is n=2,l=1,m=0,s=+21.
Which set of quantum numbers is not allowed quizlet?
The disallowed set of quantum numbers is n = 2, l = 0, ml = −1, which does not meet all the rules for acceptable values of quantum numbers because for l = 0, ml can only equal 0. n = 2, l = 1, ml = 0; n = 1, l = 0, ml = 0; and n = 3, l = 2, ml = −2 are all allowed sets of quantum numbers.
Which quantum number determine the energy of an electron?
principal quantum numberThe principal quantum number, n, describes the energy of an electron and the most probable distance of the electron from the nucleus. In other words, it refers to the size of the orbital and the energy level an electron is placed in.Jan 17, 2021
Which quantum number determines the energy of an electron in a hydrogen atom 1 point NE ML LN and L?
Answer and Explanation: Where n has a value 1,2,3, which denotes the quantum number that quantizes the energy. When light energy is provided to the electrons, it gets excited to higher energy levels. The excited electrons come back to the lower energy levels, leading to the release of light energy.
What are the quantum numbers that determine the energy of an electron in an atom?
To completely describe an electron in an atom, four quantum numbers are needed: energy (n), angular momentum (ℓ), magnetic moment (mℓ), and spin (ms). The first quantum number describes the electron shell, or energy level, of an atom.
What is quantum mechanical description of an atom?
The quantum mechanical model of the atom uses complex shapes of orbitals (sometimes called electron clouds), volumes of space in which there is likely to be an electron. So, this model is based on probability rather than certainty.Mar 26, 2016
What did the quantum mechanical model prove?
The Schrödinger wave equation proved mathematically that the energy of an electron must be quantized. The quantum mechanical model of the atom describes the probability that an atom's electrons will be located within certain regions called orbitals.Aug 2, 2012
What are electrons described as in the quantum mechanical model quizlet?
In the Bohr Model, the electron is treated as a particle in fixed orbits around the nucleus. In the Quantum Mechanical Model, the electron is treated mathematically as a wave.
What are the different types of electromagnetic waves?
electromagnetic wave. List the following types of radiation from lowest frequency to highest frequency: microwave, X ray, ultraviolet, visible, and infrared. microwave < infrared < visible < ultraviolet < X ray. The frequency of a photon is inversely proportional to the wavelength of the radiation.
Do electrons pair in degenerate orbitals?
Electrons will not pair in degenerate orbitals if an empty orbital is available and, according to Hund's rule, the degenerate orbitals must all contain one electron before any of them can contain two electrons.
