Honors Chemistry Final Exam 2025
Questions and Answers
How are monatomic ions named? - ANSWER-the elements beginning + ide (ex.
chloride)
How are binary compounds named? - ANSWER-Cation first followed by the
anion
How can one determine the subscripts in binary compounds? - ANSWER-cross
over the elements charges (the superscript) and put them as the subscript for the
other element
divide by a g.c.f. if possible
(ex. Al^+3 O^-2 turns into Al₂O₃)
When is -ate used? - ANSWER-for the ion that has the largest number of oxygen
atoms
When is -ite used? - ANSWER-for the ion with the smaller amount of oxygen
atoms

,When is per- used? - ANSWER-for the ion with one more oxygen atom than the -
ate ion
When is hypo- used? - ANSWER-for the ion with one less oxygen atom than the -
ite ion
what does -ide indicate? - ANSWER-there are two elements in the compound
oxidation numbers - ANSWER-assigned to atoms that make up a compound or
ion to indicate the distribution of electrons among the bonded atoms in a
molecular compound or polyatomic ion
prefix system - ANSWER-the first element is the element that appears first in the
periodic table and has a prefix only if it contributes more than one atom
the second element has a prefix showing the number of atoms contributed with -
ide at the end
(ex. CO₂ = carbon dioxide)
stock system - ANSWER-a roman numeral is used after the ions name to show the
ion's charge when the ions of an element can form more than one positive charge
(ex. FeCl₃ = Iron(III) chloride)
molecular geometry - ANSWER-the 3D arrangement of a molecule's atoms
VSEPR theory - ANSWER-states that repulsion between the valence electron sets
surrounding an atom causes them to be oriented as far apart as possible

, dipole - ANSWER-a molecule created by equal but opposite charges that are
separated by a short distance
linear - ANSWER-2 bonds, 0 lone pairs
trigonal-planar - ANSWER-3 bonds, 0 lone pairs
bent/angular - ANSWER-2 bonds, 1 lone pair OR 2 bonds, 2 lone pairs
tetrahedral - ANSWER-4 bonds, 0 lone pairs
trigonal-pyramidal - ANSWER-3 bonds, 1 lone pair
ionic compound - ANSWER-a compound composed of positive and negative ions
that are combined so the numbers of the charges are equal
formula unit - ANSWER-the simplest collection of atoms from which an ionic
compound formula can be written
molecule - ANSWER-a neutral group of atoms held together by covalent bonds
molecular compound - ANSWER-a chemical compound whose simplest units are
molecules
octet rule - ANSWER-chemical compounds tend to form so that each atom has an
octet in its highest occupied energy level
electron-dot notation - ANSWER-valence electrons of an element's atom are
indicated by dots placed around the element's symbol
