What contribution did John Dalton make to atomic theory? 

• He discovered that every atom was positively charged. 
• He discovered that every element consisted of one type of atom.  
• He discovered that atoms had nuclei. 
• He discovered that atoms could be divided into smaller parts.

J.J. Thomson provided evidence that an atom...

• is the smallest particle of matter
• contains negatively charged particles
• has an overall negative charge
• has an overall positive charge

NGSS.MS-PS1-1

Rutherford's gold foil experiment provided evidence that...

• 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.

NGSS.MS-PS1-1

A change in one or more physical properties of matter without any change in the chemical properties. The matter does not change into a different substance.

• Chemical Change
• Physical Change
• State of Matter Change
• Freezing Point

If you had a sealed bottle of water, how would the mass of the water bottle change after a 5 day period?

• Mass would increase. 
• Mass would stay the same. 
• Mass would decrease. 
• None of the above.
