Periodic Trends Quiz

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

As you move across the periodic table from left to right, the atomic radius decreases.  This is because - 

• the number of protons increases, so attraction to electrons increases
• the number of energy levels increases
• the number of electrons increases
• the atomic mass increases

As you move across the periodic table atoms tend to get smaller because, ______________.

• the atoms have more mass.
• the atoms have less mass

The energy required to remove electrons is the definition of: 

• Electronegativity
• Atomic Number
• Atomic Radius
• Ionization

Families all have similar 

• Names
• atomic numbers
• atomic masses
• properties
