(C) The atomic number of element $X$ is $7.$ Its electronic configuration is $1s^2 2s^2 2p^3,$ which means it has $5$ valence electrons. According to Lewis dot structure,the $5$ valence electrons are represented by placing dots around the symbol $X.$ Two electrons are paired,and three are unpaired,represented as $:\,\mathop {\mathop X\limits^. }\limits_. .$.
