Negative and positive charges are spread evenly throughout the atom.

Alpha particles have a positive charge.

Gold is not a dense as previously thought.

There is a dense positively charged nucleus at the center of an atom.

Use a large amount of candy in the center with random candies in 3D standing wave like formations.

Place candy randomly at will.

Put candies in a giant circle

Use a large amount of candy in the center with random candies in circles around the center.

The nucleus would only hold protons and no neutrons.

Electrons would be believed to be orbiting the nucleus in circular paths rather than 3D standing waves.

Electrons and Protons would be held together within the atom.

Absolutely nothing.
