What is electron configuration? - (ANSWER)the arrangement of electrons in the
orbitals of an atom
Why do ions have different sizes even though they contain the same number of
electrons? - (ANSWER)as the number of protons increases, the ionic raddi
decreases, showing that the attraction between the nucleus and an ion's electron
increases
What is the Aufbau Principle? - (ANSWER)The Aufbau principle explains that an
atom's electrons will first fulfill the subshell with the lowest available energy
before filling the subshells with higher available power

Based on their positions in the periodic table, predict which has the smallest first
ionization energy: Li, Cs, N, F, or I. - (ANSWER)Cs
List the following ions in order of increasing radius: Be2+, Mg2+, Br-, and Te2-. -
(ANSWER)Be2+ < Mg2+ < Br- < Te2-
What does it mean to have a linear molecule? - (ANSWER)two bonds and 0 lone
pairs that share a 180-degree angle
