The image depicts _ in which light behaves like a __

1

Arrange the models of the atom in order of how they were discovered.

1

In the early 1900's many scientists thought that an atom consisted of a positive substance with negative charges scattered throughout the substance. Then Ernest Rutherford completed an experiment that changed the concept of an atom. His discovery led to the understanding that an atom consists mostly of empty space with ---

Explain how Rutherford’s Gold foil experiment led to the discovery of the nucleus.

1

Which is true for the image provided?

1

While English phsysicist J.J. Thomson was carrying out experiments on cahtode rays, he was able to determine that the rays consisted of particles he called "corpuscles." These particles were later named___________

Sodium
Fluorine
Contains many gases
Conducts electricity in solids
Tends to lose electrons to from + cations
Tends to gain electrons to form - anions

Metal
Nonmetal

If X represents a metal in group 2, why is the general formula shown as XO and XF2 when element X forms a compound with either O or F?

(Hint: Pick an element in group 2 and bond it with O and then with F and compare)

In the image, we see a sodium (Na) and water (H20) reaction in slow motion.

Use the positions of Na, H and O on the periodic table to explain why sodium reacts so violently with water.
