multiple choice 1 point\nhow many valence electrons does nitrogen have in the ground - state (neutral)?\n1\n5\n2\n7
Answer
Explanation:
Step1: Recall nitrogen's atomic number
Nitrogen has atomic number 7.
Step2: Write electron - configuration
The electron - configuration of nitrogen (N) in the ground state is $1s^{2}2s^{2}2p^{3}$.
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 the $n=2$ shell is $2 + 3=5$.
