Chemistry

ATI TEAS Science Chemistry is the focus of this page, and it's here to help you build the foundational knowledge you need to feel confident heading into test day. Chemistry questions on the TEAS Science section cover core concepts like atomic structure, the periodic table, chemical bonding, reactions, and the properties of matter. If those topics feel fuzzy right now, you're in the right place. This page is designed for pre-nursing and allied health students who are preparing to sit the ATI TEAS and want targeted, focused practice in chemistry specifically.

Chemistry can feel intimidating, especially if your last science class was a while ago. The good news is that the TEAS doesn't expect you to be a chemist — it tests whether you understand key concepts well enough to apply them in a health science context. That means you don't need to memorize every element or balance complex equations from scratch. You need clear explanations, well-organized content, and enough practice to recognize what a question is really asking. That's exactly what this page delivers.

Whether you're just starting your TEAS prep or you've already studied and want to shore up a weak spot, this page gives you a focused way to work through chemistry material at your own pace. Start a practice session today to see which concepts you've got down and which ones need a second look. The sooner you identify the gaps, the more time you have to close them before your exam.
