What is the lewis dot structure of the common ion for sodium?

Explanation:

Sodium belongs to the group 1A, the alkali metals. Each element in that group possesses only one valence electron. Since metals tend to lose their electrons upon forming cations to lose their overall valence shell and have an octet in the previous shell, this means sodium will lose its single cation to remove its valence shell.

Since one electron will be lost, sodium will become positively charged, that is, sodium with a charge of +1.

Since the only electron was donated, no electrons appear in the Lewis dot structure. The image is shown below.

explanation:

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
