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.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
