How is the image that you see through the lens different from images that you see using your eye?

the image you see through a lense is different then you see with your eye because the lense is stained a certain way to prevent exposure to dangerous things because it filters it out, also its because the lense were made a special way with certain chemicals that also produce that effect, meaning that the color spectrum is different when you look at certain things with a lense.

Explanation:

Since a chemical bond has two electrons, the “number of bonding electrons divided by 2” is by definition equal to the number of bonds surrounding the atom. So we can instead use this shortcut formula: Formal Charge = [# of valence electrons on atom] – [non-bonded electrons + number of bonds]
