I discovered that  atoms are mostly ____________.

In Rutherford's experiment, a thin gold foil was bombarded with alpha particles, what was his hypothesis?

My model differed from Thompson’s model because the protons were in the ______, not spread out with the electrons.

In 1897, he demonstrated that ______ ____, which were unknown at the time,  were made of unknown negative charges.

J. J. Thomson’s experiments provided evidence that atoms are made up of even smaller particles. He found particles within the atom that have a ________ charge.

Thomson is usually credited for finding the first evidence of _____. (He did this while testing with canal rays, commonly referred to as or positive ions.)

Rutherford discovered that the positive charges of an atom were located in a tiny, more massive area in the center of the atom in what year?

In what year did Ernest Rutherford conduct an experiment to study the parts of the atom? (His experiment suggested that atoms have a nucleus—a small, dense center that has a positive charge and is surrounded by moving electrons. Rutherford later found that the nucleus is made up of smaller particles. He called the positively charged particles in the nucleus protons.)​

Thomson discovered the electron and created the plum pudding model in this year.

I am a negatively charged particle.

The electrrons are located here.

I am a positively charged particle.

These two particles make up the nucleus.

These particles have no charge.
