What does the 6 represent?

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

Ionization energy is the...

• energy needed to remove the outermost electron.
• ability of an atom to attract electrons from another atom.

Electronegativity is the...

• energy needed to remove the outermost electron.
• ability of an atom to attract electrons from another atom.

Which element has the greatest ionization energy: Aluminum (Al)    or    Chlorine (Cl)?

• Aluminum (Al)
• Chlorine (Cl)

As you move down a group, atomic radius increases because - 

• you add more and more neutrons
• you add more and more protons
• you add more and more shells (energy levels)
• you add more atomic mass

The atom with the largest atomic radius in Group 18 is - 

• Ar
• He
• Kr
• Rn

The element with the smallest ionization energy in Period 6 is - 

• Rn
• Cs
• Os
• Tm

Families all have similar 

• Names
• atomic numbers
• atomic masses
• properties

Which has the greater Electronegativity: 
N or C?

• C
• N

Which of the following will have a larger radius than Gallium (Ga)?

• Ge

• Al

• Mg

• Sr
