Question

based on the location of nitrogen (n) on the periodic table, how many additional electrons does a nitrogen atom need in its valence shell to satisfy the octet rule when it forms bonds?
one
three
five
eight

Explanation:

Step1: Determine valence electrons of nitrogen

Nitrogen (N) has an atomic number of 7. Its electron configuration is \(1s^{2}2s^{2}2p^{3}\). The valence shell (second shell here) has 5 electrons.

Step2: Apply octet rule

The octet rule states that atoms tend to have 8 electrons in their valence shell. To find the number of additional electrons needed, we use the formula \(8 - \text{number of valence electrons}\). So, \(8 - 5=3\).

Answer:

three
