Question

1. element z is in group 15, period 6. using periodic trends, which prediction about element zs properties compared to nitrogen (group 15, period 2) would be most accurate? element z will have more valence electrons than nitrogen and be more metallic. element z will have the same number of valence electrons as nitrogen and be more metallic. element z will have fewer valence electrons than nitrogen and be less metallic. element z will have the same number of valence electrons as nitrogen and be less metallic.

Explanation:

Elements in the same group have the same number of valence electrons. Nitrogen and element Z are in Group 15, so they have the same number of valence electrons. Metallic character increases down a group. Since element Z is in Period 6 and nitrogen is in Period 2, element Z is more metallic.

Answer:

Element Z will have the same number of valence electrons as nitrogen and be more metallic.
