Topics Covered In The Chemistry Section

Understanding the TEAS test chemistry concepts in as many topics as possible sets you up to succeed in the exam. Here is an overview of the examinable issues you can expect in the chemistry section:

1. Phase changes

This topic discusses different matter-phase changes, such as freezing, condensation, vaporization, sublimation, and melting. Phase changes typically happen when pressure or temperature is altered, ultimately affecting how the molecules interact. These changes entail energy transformations, with some processes being exothermic (freezing) and others being endothermic (sublimation).

2. Chemical bonds

The topic of chemical bonds discusses the fundamental principles of chemical bonding and examines the types of bonds between atoms and molecular shapes. Ensure you explore the different subsections, including covalent bonds, the formation of ionic bonds, atomic structure, bonding, and intermolecular forces.

3. Periodic Table of Elements

An effective TEAS chemistry preparation strategy has to explore the periodic table of elements. It consists of elements with different chemical properties. As you prepare for the TEAS test, review the element classification, periodic law, element properties, periodic trends, and element classification. These subsections on the topic will give you a comprehensive understanding of the properties, organization, and trends of different elements, as shown in the periodic table.

4. Acids and Bases

When studying acids and bases, start with their properties, such as their reactivity to indicators, conductivity, and pH. Explore acid-base reactions, pOH and pH, titrations, acid and base strengths, and buffers. Also, understand that acids typically donate protons, while bases accept protons. Bases are bitter-tasting and accept protons or donate a pair of valence electrons to create a bond. Acids taste sour and turn blue litmus paper red. They also neutralize bases to create salts.

5. Catalysts and Enzymes

Catalysts increase the reaction rate of a substance without being consumed, while enzymes are particular biological catalysts. The topic of catalysts and enzymes covers enzyme kinetics, regulation, inhibition, and applications. Ensure you understand how catalysts are crucial for maintaining life processes by accelerating reactions and how enzymes reduce the activation energy required for reactions, thus speeding up essential processes in living things.

Try some example questions from the TEAS practice test to familiarize yourself and learn how to answer them correctly.

Chemistry is critical in healthcare since it contributes to developing medical equipment, pharmaceuticals, and diagnostic processes. Chemists are responsible for researching, developing, and testing medications to ensure their safety in inpatient use.

Essential Chemistry Concepts for TEAS Test Preparation

This section covers the TEAS test chemistry concepts you must examine when revising for the exam. These concepts are examinable, and you will most likely encounter a question or two about them.

1. Atomic Structure and The Periodic Table

An atomic structure contains a nucleus where the neutrons and protons are found. The electrons that revolve around the nucleus can also be found here. Neutrons have no charge, while protons are positively charged subatomic particles. Electrons, on the other hand, are negatively charged and are much smaller than neutrons or protons.

As you work on your TEAS test chemistry preparation, do not forget to familiarize yourself with the periodic table. From studying this table, you will better understand how elements behave and relate to one another. The periodic table organizes elements based on their properties, allowing students and scientists to predict the characteristics of these elements and how they react.

2. Chemical Bonding and Molecular Structure

You need to understand the types of chemical bonds and their entailments fully. Three types of chemical bonds are metallic, covalent, and ionic.

Ionic bonding involves the transfer of an electron from one atom to another, which results in the attraction of ions with opposite charges. Covalent bonding involves two atoms that share electrons, forming a new orbit around both atoms’ nuclei and creating a molecule. Metallic bonding is when metal atoms bond to form a crystal lattice structure that conducts heat and electricity.

3. Chemical Reactions and Stoichiometry

Balancing chemical equations entails balancing the number of atoms on both sides of the equation. Balancing equations is vital since it obeys the law of conservation of mass, which holds that matter cannot be destroyed or created in a chemical reaction.

You could use conventional or algebraic balancing methods to balance a chemical equation. In the traditional method, you must obtain the unbalanced equation and then assign stoichiometric coefficients to the products and reactants to balance the total number of atoms.

Molar mass and mole ratio are among the key concepts for TEAS chemistry that students should look at when preparing for the exam. To calculate molar mass, you only add the molar masses of component atoms in a specific substance. Molar mass means the mass in grams of 1 mole. With this information, you are one step closer to passing the science section for the TEAS test.

4. Acids and Bases

These components showcase different properties that exhibit their differences. Acids have below-7 pH values, are corrosive, and have a sour taste, while bases have above-7 pH values, are slippery, and have a bitter taste. Acids usually turn blue litmus paper red, while bases turn red litmus paper blue.

It is also crucial to understand the pH scale. It measures the basicity or acidity of a solution. The scale ranges from 0 to 14, with a pH OF 7 being neutral, above 7 being acidic, and below 7 being basic. Polish up on this topic to have an easy time during your TEAS test.


The TEAS test is essential to your nursing career as it determines whether you will join your dream institution to become a decorated nurse. That is why it is crucial to focus on the test and prepare well. The chemistry section, in particular, is somehow challenging for most students.
