Structure of the Atom

What is the current model for the atom?

The current model for the atom consists of negatively charged electrons orbiting a positively charged nucleus. The nucleus consists of neutrons and protons that are very tightly bound to each other by a strong force. Orbiting electrons behave something like a cloud surrounding the nucleus, and we can’t be sure quite where they are at any given time. The electrons are also very lightweight compared to the nucleus, and they move much, much faster.
