Yes.

Explanation:

Number of protons = number of electrons.
Number of neutrons = mass number - number of protons

First electron shell can only hold a maximum of 2 electrons.
Second and third electron shell can only hold a maximum of 8 electrons.

Since all the rules above are followed, the structure is correct.
