PLEASE HELP!
Name two elements that have the Lewis dot diagram shown in the image.

Nitrogen and Phosphorus

Explanation:

Generally as we know, the lewis dot diagrams for elements use the number of valence electrons that the element has

From the diagram above, we can see that the element in question has 5 valence electrons

so therefore, we need two elements with 5 valence electrons

These are elements are nitrogen (2,5) and phosphorus (2,8,5)

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).
