http://hyperphysics.phy-astr.gsu.edu/hbase/molecule/NaCl.html Web23 sep. 2013 · As a result, electrons in an atom take different states, starting from the lowest energy state and going upwards in energy until the electrons have all found distinct states. For various reasons that are not worth mentioning here, electron states in atoms tend to form various groups, with the states in the same group having very similar energies and …
What is the net ionic equation for NaCl plus H2O? - Answers
Web24 feb. 2012 · When particular chemical substances are added to water – for example, sodium chloride (NaCl) – they get dissolved and their molecules get split into negative and positive ions. This process of … Web20 jan. 2014 · It is an ionic bond created by an attraction between the +1 sodium cation and the -1 chlorine anion. Sodium which has an electron configuration of 1s22s22p6 and 3s1. The sodium will readily give away the one electron in the 3 s orbital in order to stabilize the outer shell and become like the noble gas neon. green color magick
Explain the steps involved in Born Haber cycle for the formation of NaCl.
WebFor example, NaCl(s)Na+(g)+Cl(g)H=786kJ/mol Assume that the ionization energy and electron a affinity are H values for the processes defined by those terms. The ionization energy of Na is 496 kJ/mol. Use this, the electron affinity from Table 8.4, and the lattice energy of NaCl to calculate H for the following process: Na(g)+Cl(g)NaCl(s) WebStep 1: Sublimation of metallic sodium of gaseous sodium atom with the enthalpy of sublimation = H sNa(s)→Na(g); H= H sStep 2 : Dissociation of molecule of chlorine to chlorine atoms with enthalpy of dissociation = H d21Cl 2(g)→Cl(g); H= H dStep 3: Ionization of gaseous sodium with the enthalpy of ionization = H iNa(g)→Na +(g)Step 4 ... WebBut is this exchange energetically favorable ? Let us look at the case of NaCl Ionization energy of Na atom ~ 5.1 eV (energy needed to separate the outermost electron) Electron affinity of Cl atom ~ 3.6 eV (energy reduction on gaining extra electron) So - a net input of 1.5 eV (~ 5.1 - 3.6 ) is required to create a NaCl bond. flow soporte
