When we talk about electricity, we are talking about:

The movement of electrons to create a charge.

The planetary model could not explain why:

Atoms only emit light at certain frequencies.

In an atom the number of electrons is usually:

The same as the number of protons.

Niels Bohr solved the problem of the planetary model by discovering that:

Electrons only orbit the nucleus in fixed energy levels.

The "plum pudding model" suggested that an atom was made of:

A positive charge with negatively charged particles inside.

Which part of the "billiard ball model" do we now know to be incorrect?

The atom is the smallest possible particle in the universe.

This is our current best picture of what an atom looks like:

Far out!, Woah., Dude., Awesome!!!
