Chemistry Review

The atomic number tells you what?

• number of electrons
• number of protons
• number of neutrons
• both electrons and protons in an atom.

If an atom had the same properties as fluorine (F), it would probably be located in

• period 1.
• period 2.
• group 2.
• group 17.

Atoms with similar properties are most likely located...

• in the same period.
• in the same group.
• in different periods.
• to the right and left of each other.

what does the 6 represent?

• Atomic mass
• atomic number
• chemical symbol
• element name
