how many valence electrons are in an atom of nitrogen? enter the answer check it
Answer
Explanation:
Step1: Recall nitrogen's atomic number
Nitrogen has atomic number 7.
Step2: Determine electron - configuration
The electron - configuration of nitrogen is 1s²2s²2p³.
Step3: Identify valence electrons
Valence electrons are in the outermost shell. For nitrogen, the outermost shell is the second shell (n = 2), and the number of electrons in n = 2 is 2 + 3=5.
