Question

select the correct answer.nitrogen is a group 15 element. what does being in this group imply about the structure of the nitrogen atom?a. nitrogen has 15 valence electrons.b. nitrogen has 15 neutrons.c. nitrogen has 5 valence electrons.d. nitrogen has 5 neutrons.

Explanation:

Group numbers (for main group elements) correspond to the number of valence electrons an element has. Group 15 elements have 5 valence electrons. Neutron count depends on the specific isotope of nitrogen, not its group, and nitrogen's atomic number is 7, so its typical neutron count is 7 (for nitrogen-14). Option A is wrong because 15 is the group number, not valence electron count.

Answer:

C. Nitrogen has 5 valence electrons.
