TEAS-Chemistry Exam 102Questions and
Answers (Latest Update 2025/2026)GRADED
A+
matter - CORRECT ANSWERS objects that take up space and have mass. made up of elements.
physical thermal electrical and chemical properties (color, density,hardness,conductivity)
elements - CORRECT ANSWERS substances that cannot be broken down into simpler
substances by chemical means.
atoms&molecules - CORRECT ANSWERS everything in the physical world is make up of
microscopic matter comprised of atoms or molecules.
homogenous matter - CORRECT ANSWERS properties are the same throughout. coal and glass
are examples
heterogenous matter - CORRECT ANSWERS properties may vary in their make-up. concrete
and soil are examples.
atoms - CORRECT ANSWERS the tiniest unit an element retains its characteristic properties.
building blocks. they have protons, neutron, and electrons.
nucleus - CORRECT ANSWERS core of an atom. protons and neutrons are particles that are
packed together here.
protrons - CORRECT ANSWERS positively charged
neutrons - CORRECT ANSWERS uncharged or neutral
, electrons - CORRECT ANSWERS negatively charged particles that orbit outside of nucleus. in
constant motion. small compared to protons and neutrons.
neutral atom - CORRECT ANSWERS the number of electrons is equal to the number of
protrons: the charges inside and outside the nucleus are balanced.
isotopes - CORRECT ANSWERS atoms have same number of protons but differ in number of
neutrons in the nucleus.
ion - CORRECT ANSWERS when an atom loses or gain one or more electrons on the outside so
the nucleus is not equal to the number of protons on the inside.
cation - CORRECT ANSWERS atoms loses one or more electrons it becomes positively charged.
anion - CORRECT ANSWERS atoms gain one or more electrons it becomes negatively charged.
gas phase - CORRECT ANSWERS matter has neither definite shape nor definite volume
liquid phase - CORRECT ANSWERS matter has a definite volume but an indefinite shape. take
the shape of heir containers.
solid phase - CORRECT ANSWERS matter has both definite shape and definite volume
liquids&solid - CORRECT ANSWERS condensed phases because the particles are very close
together.
properties of gas - CORRECT ANSWERS assume shape and volume of closed container.
