6.1 Lab Sticky tape

Sticky tape lab: The bottom tape was in place on the table. You smoothed the top tape on top of the bottom tape. The tapes are both still on the table. What happened?

• Nothing much

• Electrons moved from one tape to another

• The sticky part of the top tape got stickier

When electrons moved from one tape to the other tape, which way did they move?

• From the top tape to the bottom tape

• From the bottom tape to the top tape

• Some moved from top tape to bottom tape, and others moved from the bottom tape to the top tape

Where is the positive charge in an atom?

• In the electrons

• Throughout the atom

• There isn't a positive charge

A neutral atom--

• Has the same amount of negative charge as positive charge

• Has no electrons and no positive charge

• Has exactly three electrons

Who first described the plum pudding model of the atom?

• John Newlands

• J.J. Thomson

• Dmitri Mendeleev

How did you know that F (foil) and P (paper) strips were not charged?

• They repelled another tape

• They did not repel any other tapes

• They attracted another tape like themselves

If a strip X attracted F, P, and B, but repelled T, the charge of X is--

• The same as T

• The same as B

• Can't tell; I need more information
