Question

how many covalent bonds is nitrogen (group 5a) likely to form? (1 point)
four
five
three
two

Explanation:

Step1: Find valence electrons of N

Nitrogen (Group 5A) has 5 valence electrons.

Step2: Calculate needed electrons for octet

Atoms need 8 valence electrons for a full octet (stable state). Electrons needed: $8 - 5 = 3$.

Step3: Relate to covalent bonds

Each covalent bond shares 1 electron, so 3 bonds give 3 shared electrons, completing the octet.

Answer:

three
