Unit 1.5: Atomic Structure and Electron Configuration
Identify the location of subatomic particles and the charge of areas of
the atom.
-
Where are protons, neutrons, and electrons located in an atom, and
what charges do they have?
Qualitatively apply Coulomb’s law and effective nuclear charge to
justify differences in attractive force between nucleus and core vs.
valence electrons.
- Why are valence electrons easier to remove than core electrons?
Write the electron configuration for an atom or ion.
- Write the electron configuration for O²⁻.
Determine the number of unpaired electrons in an atom.
- How many unpaired electrons are in a nitrogen atom?
Differentiate electronic structure in terms of shells and subshells.
-
What is the difference between the 2s and 2p subshells in terms of
energy and shape?
Qualitatively apply Coulomb’s law to discuss differences in ionization
energy by comparing electron shells/subshells between atoms.
- Why does helium have a higher ionization energy than lithium?
