Exam I Online Key & Solution
Q1
Q2
, Q3
The atomic number of N is 7.
So the electronic configuration is
1s22s22p3
The valence electrons are 5.
There are three sigma bonds that N has, which
means that N provides three electrons (each
single bond has two electrons). So 5 - 3 = 2
electrons (1 lone pair) are on N.
