Small particles don't obey classical physics. In the quantum landscape, electrons do not have a precisely defined position. The orbital represents a probability distribution- you may see it as a spatial map of where the electron is likely to be on average, but you cannot freeze time and say...
Energy of an electron in an excited state of hydrogen atom is - 3.4 eV. Its angular momentum will be A1.11×10−34 Js B1.51×10−34Js C2.11×10−34Js D3.72×10−34JsSubmit The energy of electron in an excited hydrogen atom is −3.4eV. Its angular momentum according to bohr...

electron affinityEnergies and g -factors of the ground states of a zirconium atom and its negative ion and energy of electron affinity to a neutral atom are calculated. The method used represents a combination of the superposition of configurations and the determinant perturbation theory. A ...
Question. The ionization energy of the electron in the hydrogen atom in its ground state is 13.6 eV. The atoms are excited to higher energy levels to emit radiations of 6 wavelengths. Maximum wavelength of emitted radiation corresponds to the transition betweenC a) n = 3 to n = 1 states...
When an electron in an atom falls from higher orbit to a lower orbit a photon gets emitted. Since the electrostatic potential-energy of the electron is negative, because of the attractive force between the proton and the electron, the fall of electron makes its potential-energy more negative....
aThe first ionisation energy of an element is the energy required to remove one electron from each atom in a mole of atoms of the element in the gaseous state 元素的第一游离能是要求的能量从每个原子去除一个电子在元素的原子痣在气体状态[translate]...
(f) For a carbon atom, the binding energy of an electron is of the order of a few electronvolts.Compton's theory assumes that the electrons are not bound in the atoms but are free.Suggest whether, for 30 keV photons, this assumption is justified... [2][Total: 20] 相关知识点: ...
An atom has an electron configuration of 1s22s22p5. How many electrons are in that atom? In K_4(Fe(CN)_6], how many electrons are there in the d orbital of the iron atom? How many core electrons are in an As atom? What is the maximum number of electrons...
Atom RSS Feed Featured Electron spin matters Electrolytic hydrogen production using conventional electrocatalysts suffers from low energy efficiency, due in part to the sluggish nature of the oxygen evolution reaction (OER). Topological chiral semimetals are now explored to facilitate the OER by promoting...
