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: Find nitrogen's group number

Nitrogen is in Group 15 of the periodic table.

Step2: Determine valence electrons

Group 15 elements have 5 valence electrons.

Step3: Calculate needed electrons for octet

Octet rule requires 8 valence electrons. Subtract existing valence electrons: $8 - 5 = 3$.

Answer:

B. three
