Explanation Lewis Symbol : The Lewis symbol is written with help of valence electrons. Each of the valence electrons are arranged over the atom by a dot. If the valence shell has paired electrons, the pair will be shown as lone pair of dots over the atom and if the electrons are unpaired, then they will be shown as single dots over the atom. Given: a. Aluminium (Al) : We have the element nitrogen (Al). Electronic configuration : We know that Aluminium has an atomic number of 13 for which the electronic configuration can be written as follows: A t o m i c n u m b e r = 13 N u m b e r of electrons =13 Electronic cnfiguration=1s 2 2 s 2 2 p 6 3 s 2 3 p 1 valence electrons=3 ( 3 s 2 3 p 1 ) c o r e electrons=10 (1s 2 2 s 2 2 p 6 ) Here, the outermost orbital has 3 electrons which will be shown in Lewis symbol. Since 3s-orbital is filled so two 2s- electrons will be shown as pair of dots representing the lone pair over Al-atom while the one unpaired electron of 3p-orbitals are shown as an individual dot over the atom as follows: b. Sodium Ion (Na + ) : We have the Sodium ion (Na + ). Electronic configuration : We know that sodium has an atomic number of 11 which looses one electron to form sodium ion for which the electronic configuration can be written as follows: A t o m i c n u m b e r = 11 N u m b e r of electrons =11 Electronic cnfiguration(Na)=1s 2 2 s 2 2 p 6 3 s 1 Electronic cnfiguration ( N a + ) = 1s 2 2 s 2 2 p 6 3 s 0 Here, the outermost 3s-orbital has no electron in the sodium ion, so the Lewis symbol will have no dot over the structure, however, a positive charge will be written as superscript as follows:
