Nitrogen's atomic number is equal to 7.
Explanation:
Nitrogen is located in group 15, period 1 of the periodic table, and has an atomic number equal to 7.
In order to get an element's atomic number, you need to know how many protons it has in its nucleus.
A neutral nitrogen atom has seven protons in its nucleus and seven electrons surrounding its nucleus.
Remember that elements are arranged in the periodic table in order of their atomic mass, which means that you can also determine an element's atomic number by looking at its position in the periodic table, if you happen to have one close by.
