Known as the central science study of matter and its composition

5 types of chemistry

from Chemi (Soil from Egypt) meaning “cast together”

Means “Dark Arts”

From arabian extension “Al” and Kem-mai meaning “Lost for gold searching”

occupies space and has mass

Particles that are tightly packed and have regular arrangement

Particles are tending to hold and usually hold the shape of its container

Particles are dispersed and loosely packed

Ionized gas whose energy is sufficient to release atoms

Occurs at very low temperature in which particles tend to stop at moving

Matter with definite composition and distinct properties

Contains one kind of atom

Pure substance that contains 2 or more elements combined with definite proportion by mass

Matter of microscopic composition

Building blocks of matter

two or more atoms combined chemically

Composition of two or more pure substances

Composition is uniform throughout the substance. Components are indistinguishable

Composition varies and thus has particles that retain their chemical properties

Solid material did not dissolve in liquid mixture

Particles (between 1 to 1000 nm) did not dissolve in liquid mixture

Properties that are measurable without changing the identity of the substance

Properties that are measurable by the production of another substance

Evidence of Chemical Reaction

Properties that are dependent to the size of the sample

Properties that are independent to the size of the sample

the quantity of matter in a particular sample.
