4 cards from this section. Quick, good the night before a test.
How many electrons can the K shell hold?
Recall the formula for maximum electrons in a shell.
Which shell is filled first in an atom?
Remember the filling order of the shells.
What is the maximum number of electrons in the L shell?
Use 2n² to find the answer.
True or False: The M shell can hold more electrons than the L shell.
Recall the maximum limits for each shell.
For an atom with 20 electrons, draw the electron configuration and explain how it adheres to the 2n² rule.
Remember to break it down by shell.
If an atom has 5 valence electrons, describe its likely bonding behavior and reference the Octet Rule.
Consider how many it needs to reach 8 valence electrons.
