Step 1:
Step 2::
To determine the number of valence electrons in nitrogen, we first need to identify its position in the periodic table. Nitrogen is in the 15th group of the periodic table, which corresponds to the p-block elements.
Step 3:
Step 4::
The number of valence electrons in p-block elements is equal to the group number. This is because the outermost energy level of p-block elements contains 5 electrons, and the group number represents the total number of electrons in the outermost shell.
Step 5:
Step 6::
Therefore, for nitrogen, which is in the 15th group, there are 15 - 10 = 5 valence electrons (since the first 2 energy levels are already filled with 2 and 8 electrons, respectively).
Final Answer
Nitrogen has 5 valence electrons.
