Question
How many dots should be shown around the symbol for selenium when writing the Lewis dot structure?
Solution
When writing the Lewis dot structure for an atom, the number of dots corresponds to the number of valence electrons in the atom. Selenium (Se) is in group 16 of the periodic table, so it has 6 valence electrons. Therefore, there should be 6 dots around the symbol for selenium in its Lewis dot structure.
