Well, no. If a picture disappeared from the Library view, then you'd have a hard time finding it again to put it in an additional album. Photos works in a way that makes it possible for pictures to be "in" many albums. It makes lots of sense.
In Photos, pictures aren't exactly "in" an album. When you "put a picture into an album," its name is added to a list of pictures from the Library that display together when the album is clicked, kind of like a music playlist, but for pictures. So two albums can both have the same picture name in their lists (like two playlists with the same song,) and that picture will show up when you click either album, but there's only one picture file-- it's just on multiple lists. And when you remove a picture from an album, its name remains in the lists of other albums, and the file still remains in your Library. This allows you to organize your pictures with albums without having to exclude a picture just because it's already somewhere else.
So albums give a specific view of your pictures. The picture of "Aunt Ethel at the Grand Canyon" can be in the "Aunt Ethel" album with other pictures of Aunt Ethel, and it can also be in the "Grand Canyon" album with pictures of other people at the Grand Canyon. And it can also be in a the "September 2015" album with other things that happened then. Each album is pointing to a single file stored in the Photos Library, so having pictures in multiple albums takes up no more storage space. As you can imagine, this is very powerful in organizing pictures.
If you want to see which pictures haven't yet been assigned an album, then you can use Filters. LIke this:

In what way does this not do what you say you want?
