GEN CHEM 1 EXAM 3 QUESTIONS
WITH COMPLETE SOLUTIONS
periodic property - Correct Answers -predictable based on an element's position within
the periodic table
periodicity of atomic radius - Correct Answers -increases down columns (bigger orbitals)
and decreases across rows (bigger Zeff)
periodicity of ionization energy - Correct Answers -decreases down columns and
increases across rows
periodicity of electron affinity - Correct Answers -negligent down columns and increases
across rows (becomes more exothermic)
periodicity of metallic character - Correct Answers -increases down columns and
decreases across rows
quantum-mechanical theory - Correct Answers -describes the behavior of electrons in
atoms
ground state - Correct Answers -lowest energy state for electrons
two factors affecting how multi electron atoms occupy orbitals - Correct Answers -
electron spin and sub level energy splitting
Pauli exclusion principle - Correct Answers -no two electrons in an atom can have the
same four quantum numbers
degenerate - Correct Answers -orbitals existing with the same energy
as the value of l decreases - Correct Answers -the energy of the orbital decreases
coulomb's law - Correct Answers -potential energy of two charged particles depends on
charge and separation (1/4πE)⋅(q1q2/r)
