Which idea that was once accepted is now considered scientifically inaccurate?

A. The nucleus is the center of the atom
B. An atom is solid material
C. Electrons have a negative charge
D. Electrons are arranged in layers

The idea that an atom is solid material is now considered scientifically inaccurate. Historical theories proposed this notion, but advancements in atomic theory have revealed that atoms consist of smaller particles and mostly empty space. This understanding has evolved alongside the ongoing study of atomic structure and behavior.
