Basic Graphic Design Questions

[kat.hayes]

I'm new to the graphic design world and I have been reading as much as I can, though I'm confused by conflicting stuff I'm reading. I see a lot of pages describe the elements of graphic design as:

- lines
- shapes
- color
- texture
- value
- space

and then I have seen some pages add form/volume/mass

1.) Does the list above seem accurate? anything missing? should form/volume/mass be included as well to the elements of graphic design?

2.) What then are the following called? Are these just ways to organize the graphic design elements?
- proximity
- alignment
- repetition
- contrast/emphasis/hierarchy
- typography
- rhythm
- pattern
- proportion
- variety

Thanks!
