In this lesson, we will cover the ground state electron configuration, which determines the electron's structure. Answer Save. Indicate whether Fe 2 + ions are paramagnetic or diamagnetic. Maths. 0. Books. (b)The electronic configuration of bromine is{eq}\left[ {{\rm{Ar}}} \right]4{{\rm{s}}^2}3{{\rm{d}}^{10}}4{{\rm{p}}^5} In case of bromine the core electron resides in 1s,2s,2p,3s and 3p. How many orbitals contain one or more electrons in an isolated ground state iron atom (Z 26)? A. Co(NH3)3CI3 (low spin) B. Earn Transferable Credit & Get your Degree, Get access to this video and our entire Q&A library, Angular Momentum Quantum Number: Definition & Example. All other trademarks and copyrights are the property of their respective owners. Physics. 3a.How many electrons are predicted to be in the 4p orbital of a bromine (Br) atom? In case of bromine, the valence electron resides in 4s,4p and 3d. CopperI complexes would be expected to be colorless True False Calculate the; American University of Beirut; CHEM 201 - Fall 2009. Co H3N NH3 Br 2. This lesson defines state functions and explains why state functions are so useful in thermochemistry and thermodynamics. Biology . There are six electrons in valence shell of oxygen, among these six electrons two electrons are unpaired and involved in forming covalent bond with hydrogen and carbon, while remaining 4 electrons in pair (i.e. © copyright 2003-2021 Study.com. [Ti(H2O)6]³+ 3. FERROMAGNETIC ELEMENT. Rule 2: Hunds Rule The most stable arrangement of electrons is one with the maximum number of unpaired electrons.
