Back to the blood cell:

If we could magnify it that much,

The nucleus would be the size of…

… the pitcher’s mound? No.… the baseball?… a stitch on a baseball? Yes.

So you wouldn’t be able to see the nucleus in this picture!

(Electrons are even smaller.)

Inside the nucleusInside the nucleus

Inside the nucleus there are smaller objects called quarks and gluons.

They are never seen on their own.
