Answer
C
Explanation
The correct Lewis dot structure for a molecule of nitrogen (N2) is :N≡N: because nitrogen is a molecule consisting of two nitrogen atoms linked by a triple bond. This is represented in choice C. Other choices incorrectly represent either the number of bonds or the placement of electrons. In Lewis Dot structures, a line represents a pair of shared electrons (a bond), and the dots around the atoms represent unshared electrons. Nitrogen atom has 5 valence electrons, so 3 are shared (making up the triple bond), and 2 remain unshared.
