Answer:
Because selenium is in the 16th column on the periodic chart, it has 6 valence electrons. Thus, the Lewis structure (or electron dot structure) for selenium has 6 dots around it.
It will look similar to this without the underscores:
__.
. Se:
_. .
Explanation:
The Lewis structure (or electron dot structure) for selenium has 6 dots around it.
Electron dot diagrams are diagrams in which the valence electrons of an atom are shown as dots distributed around the element's symbol.
