Ch 7: HESI Admission Assessment Exam: Chemistry

About This Chapter

Use this chapter to prepare for the Chemistry subtest of the HESI Admission Assessment exam. You'll watch engaging video lessons on topics like the periodic table, chemical reactions and carbon dating.

HESI Admission Assessment Exam: Chemistry - Chapter Summary

This chapter contains video lessons and practice quizzes to get you up to speed for the HESI Admission Assessment Exam Chemistry subtest. Learn about atoms and elements, states of matter and chemical bonding. By the end of the chapter, you'll also have gathered information about the following:

  • Liquids, solids, gases and plasma
  • Types of phase change
  • Atoms and electron shells
  • Covalent bonding
  • The periodic table
  • Writing and balancing chemical equations and reactions
  • Radioactive decay and half-life
  • Carbon dating, fission, fusion, imaging and tracers

Our instructors have compiled a series of brief video lessons that explain essential concepts in a way that is easy to understand and remember. Follow along using the written transcripts or skim them to help you review key lesson topics. Assess what you've learned and what you still need to work on with the lesson quizzes.

HESI Admission Assessment Exam: Chemistry Chapter Objectives

The HESI Admission Assessment Exam is required to apply to most nursing schools. The exam consists of a series of subtests covering English, Math and Science. Use the resources in this chapter to get ready for the Chemistry subtest of the exam, which consists of 25 scored questions and 5 pilot questions. You'll be tested on topics like matter, the periodic table, chemical bonding, equations and reactions.

States of Matter: Solids, Liquids, Gases, & Plasma

1. States of Matter: Solids, Liquids, Gases, & Plasma

Learn the four states of matter in the universe: solid, liquid, gas and plasma. Learn about the differences in shape and volume among the four states, which of the states is the most common and why plasma conducts electricity.

Phase Change: Evaporation, Condensation, Freezing, Melting, Sublimation & Deposition

2. Phase Change: Evaporation, Condensation, Freezing, Melting, Sublimation & Deposition

Substances on Earth can exist in one of four phases, but mostly, they exist in one of three: solid, liquid or gas. Learn the six changes of phase: freezing, melting, condensation, vaporization, sublimation and deposition.

The Atom

3. The Atom

Tune into this lesson to find out what matters about matter. What exactly is an atom? And, how do the atoms that make up the elements in the periodic table differ from one another?

The Electron Shell

4. The Electron Shell

You may be familiar with the role of electrons in electrical devices, but did you know that electrons also determine the chemical reactivity of everything around you?

Covalent Bonding and Electron Shells: Definitions, Relationship & the Octet Rule

5. Covalent Bonding and Electron Shells: Definitions, Relationship & the Octet Rule

Learn about the different electron shells of atoms as well as the octet rule for valence electrons and how that applies to covalent bonding. Discover the definition of covalent bonding and the relationships between atoms.

The Periodic Table: Properties of Groups and Periods

6. The Periodic Table: Properties of Groups and Periods

How is the periodic table like the map you used on your last road trip? In this lesson, you will be introduced to the periodic table, the road map of chemists. We will discuss how the elements are organized and how you can use this organization to identify some of their major physical properties.

Overview of Chemical Bonds

7. Overview of Chemical Bonds

Learn about the most common kinds of chemical bonds: ionic, covalent, polar covalent, and metallic. Discover how they form and why they hold together. Take a quiz and see how much knowledge you've held onto.

Chemical Reactions and Balancing Chemical Equations

8. Chemical Reactions and Balancing Chemical Equations

In this lesson, you'll learn how to balance a chemical reaction equation using the conservation of matter law. You'll also learn how to write both word and formula equations, what the subscripts after a letter mean and what the numbers in front of compounds mean.

Basic Properties of Chemical Reactions

9. Basic Properties of Chemical Reactions

Learn how about the various components of a chemical reaction, and how those components function. Use this lesson to understand the basic properties of different kinds of chemical reactions.

Types of Radioactive Decay and Their Effect on the Nucleus

10. Types of Radioactive Decay and Their Effect on the Nucleus

What is meant by the term 'radioactive'? In this lesson we will break down the three main types of nuclear decay particles and discuss their composition, their effect on the nucleus, and their applications.

Half-life: Calculating Radioactive Decay and Interpreting Decay Graphs

11. Half-life: Calculating Radioactive Decay and Interpreting Decay Graphs

What causes a radioactive particle to decay? We'll never really know, but our best guess lies in probability. In this lesson, we are going to focus on the half-life, a way of measuring the probability that a particle will react.

Fusion, Fission, Carbon Dating, Tracers & Imaging: Applications of Nuclear Chemistry

12. Fusion, Fission, Carbon Dating, Tracers & Imaging: Applications of Nuclear Chemistry

What can the sun do that we can't? How do carbon atoms 'date'? Are radioactive isotopes helpful in the medical field? The answers to these questions can be found in this lesson on the applications of nuclear chemistry.
