HESI A2 Chemistry: What to Study
Elsevier’s HESI A2 Chemistry exam covers physical and chemical matter, the periodic table, chemical equations, reactions, and bonding. Confirm your program assigned it.
Short answer
HESI A2 Chemistry is one of Elsevier’s seven academic exams. Elsevier describes it as physical and chemical matter, the periodic table, chemical equations, reactions, and bonding, with 25 scored items and about 25 minutes when administered. Programs often omit it. If your school did not assign Chemistry, do not build a chemistry semester. If it did, study that published scope—not reconstructed live items.
Confirm Chemistry the same way you confirm every other module
Chemistry is in the current sixth-edition Admission Assessment review and in Elsevier’s seven-exam science group. It is still a program choice. Practice HESI A2 periodic-table and reaction items in Passy after the admissions page names Chemistry.
A classmate’s BSN list is not your list.
Elsevier’s Chemistry outline, used as a fence
Study what the publisher named:
- physical and chemical matter
- periodic table
- chemical equations
- reactions
- bonding
That supports first-year ideas such as classifying matter, reading group/period trends at a basic level, balancing a simple equation, recognizing a reaction type, and naming ionic versus covalent bonding in plain language. It does not authorize a full organic chemistry course.
Passy’s original pH-scale item is a teaching example about hydrogen-ion concentration. It is not an official HESI item and it is not a claim about how often pH appears.
A compact review loop
Elsevier estimates about 25 minutes for 25 scored Chemistry items when the exam is given. Fluency matters.
- Define element, compound, and mixture in one line each.
- State what a chemical equation is conserving.
- Describe bonding as electron sharing versus transfer at a basic level.
- Work a short original set.
- Tag misses as definition, table, equation, or reaction.
Check those Chemistry ideas beside other assigned science in Passy so a Biology cell question and a Chemistry bonding question stay distinct.
Biology and A&P are separate assigned exams. Arithmetic that appears inside a chemistry word problem still sits next to HESI A2 Math. Sequence everything with the study guide.
If Chemistry is assigned and weak, repair the missed reaction or table idea in Passy.
Do not add a university lab manual you will not finish before test day.
When the science subset is locked, keep Chemistry inside that HESI A2 outline in Passy instead of buying extra books for exams you were not assigned.
