In order to achieve the nearest noble gas configuration it gains one electron to form chloride ion.
Electron configuration of sodium and chlorine. 495 8 349 147 kj mol 1. Cl 2 8 7. Write electronic configurations of sodium and chlorine and explain the formation of sodium chloride by electron dot structure. Chlorine has 7 electrons in its outer shell.
In order to achieve the nearest noble gas configuration it loses one electron to form sodium ion. And therefore an extra negative charge shown as a sign. Electronic configuration is. When an atom of chlorine reacts it will gain one electron from.
With filled outer shells they are no longer chemically active and can t form covalent bonds to become part of a molecule. And be full. So it contains 7 valence electron. So it contains 1 valence electron.
The electronic configurations of atoms of sodium and chlorine are. Na 2 8 1. A sodium atom gives an electron to a chlorine atom. Na 2 8 1 cl 2 8 7 describe the changes in the electronic configurations of sodium and chlorine when these atoms form sodium chloride m1 na loses electron s m2 cl gains electron s.
Thus we write the lewis structure for nacl as. Sodium electron configuration notation the configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom. The result is a sodium ion 2 8 and a chloride. The outer shell of chlorine will then have 8 electrons.
The chloride ion will have an extra electron. In ionic bonds valence electrons are completely transferred not shared. As you can see chlorine since sodium is a metal it has relatively low values for ionization energy and electronegativity. Therefore the sodium electron configuration will be 1s 2 2s 2 2p 6 3s 1.
Sodium na with an electron configuration of 1s22s22p63s1 sheds its outermost 3s electron and as a result the na ion has an electron configuration of 1s 22s2 2p6. It is in group 7 of the periodic table. Atomic number of chlorine cl atom is 17. State the type of bonding formed.
Diagram of bonding in sodium chloride. The energy required to transfer an electron from a sodium atom to a chlorine atom the difference of the 1st ionization energy of sodium and the electron affinity of chlorine is small.
