Periodic Trends

You should have your HONORS Reference Tables out while completing this activity. Remember for the Honors Chemistry class, you don't need to be able to memorize the numbers but you should be able to state the trends, exceptions and reasons for both.

Which species has the largest radius? Review this video if necessary.

Ba

Mg

1

Sodium and chlorine both have 3 shells of electrons. Which statement correctly identifies and explains why the radii are different?

Cl is larger because it has 3 shells and more electrons

Na is larger because it has 3 shells but a smaller nuclear charge

1

Which species has the highest first Ioniaztion Energy?

B because the e- being one unpaired electron in the "p" sublevel

Be because it has fewer protons

B because it has more electrons

Be because the e- is being pulled from completely filled "s" orbital
