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)

wavelength divides in half and speed stays the same.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
