periodic trends part 1 CP chem

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

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

As you move down the periodic table atoms get bigger. This is because ____________.

• The atoms have more mass.

• The atoms have more protons.

• The atoms have more energy levels

• The atoms have more neutrons

Which species has the larger radius?

• Cl

• ^Cl-

Which species has the larger radius?

• Na

• Na⁺

Which is larger... P or P^3- ? … and why?

• P^3- because it gains an energy level

• P^3- due to extra electron repulsion

• P because it loses an energy level

• P because of extra electron repulsion

The more protons there are, the  ____ .

• Weaker the pull
• Smaller the electrons
• Stronger the pull
• The bigger the electrons

Which one has the largest radius?

• Lithium (Li, atomic #3)
• Boron (B, atomic #5)
• Neon (Ne, atomic #10)
• Nitrogen (N, atomic #7)

As you move down a group, shielding 

• increases because there are more  orbitals
• increases because there are more protons
• decreases because the atomic radius increases
• stays constant because the number of valence electrons stays the same
