describe one reason why models of atoms we usually see in textbooks or diagrams are not perfectly accurate representation of real life atoms

"One way atomic models are often inaccurate is that electrons are way smaller than they portray. In reality, atoms have incredibly small electrons."A proton is about 1,835 times more massive (mass not size) than an electron. An electron's physical dimensions are so small, that we will never know how small they really are.
