Multiple Choice

REVIEW: How do sodium and chlorine both achieve stable electron configurations when they react?

• an electron is transferred from sodium to chlorine

• an electron is transferred from chlorine to sodium

• both atoms gain one electron

• both atoms lose one electron

Multiple Choice

Within a period (horizontal row), what happens to the ATOMIC RADIUS as the atomic radius of the elements increases?

• it increases

• it decreases

• it stays the same

• there is no definite pattern

Multiple Choice

Within groups (columns) 1A, 2A, 6A and 7A, what happens to the ATOMIC RADIUS as the atomic number of elements increases?

• it increases

• it decreases

• it stays the same

• there is no definite pattern

Multiple Choice

How does adding an occupied energy level affect the ATOMIC RADIUS? (hint: Lithium is in period 2 and has 2 energy levels and Sodium is in period 3 and has 3 energy levels)

• adding an energy level increases the atomic radius

• adding an energy level decreases the atomic radius

• adding an energy level has no effect on the atomic radius

Multiple Choice

• it increases

• it decreases

• it stays the same

Multiple Choice

• the ionic radius is bigger

• they are the same

Multiple Choice

What happens to the atomic radius when an atom GAINS electrons?

• it increases

• it decreases

• it stays the same

​When you finish...

• ​Complete PS 6.1 Formative (at least once) before you leave. Remember to take it until you get a 10/10. The last day to complete this will be the day before our Chapter 6 Quiz (TBA).

• ​Read 6.2 in the text and add to your notes page.
