MATTER everything that occupies space and has mass
MIXTURES: variety of pure substances
Homogenous
Has a uniform composition
it's almost imposible to turn apart
heterogeneous
Two ore more substances were you can tell the difference
it's easily reversible
PURE SUBSTANCE: has fixed composition
ELEMENTS: are atoms that can't be speared in smaller pieces
joined together form
Molecules
joined with other molecules or elements form
Elements have
Density:
The ratio of mass to volume of an object
can be distinguished in room temperature by
can be distinguished in room temperature by
color
COMPUNDS: substance made by bonds of different elements
have
PHYSICAL PROPERTY: any property that can be measurable and that is involved with the state of a compound
examples are:
Color
Blue, black, yellow...
Hardness
How hard is an object
Melting and boiling point
The temperature in which an object melts and boils
Density
The ratio of mass to volume of an object
solubility
The ability to dissolve
Electric conductivity
The ability of an object to conduct electricity
Malleability
The ability of something to change shape without breaking
Ductility
The ability of an object to stretch without breaking
viscosity
The resistance of an object to deformate
can have
physical changes
in any of these properties
Changes in physical properties
CHEMICAL PROPERTIES: a chemical reaction that a particle can present
Examples are:
Atomic Number
The number of protons and neutrons atom has
Atomic Mass
The mass of an atom or element, which is presented in mass units
can have
chemical changes
reactants
change into
products
States of matter
solid
liquid
gas
Atoms
are diveded into
The smallest unit of matter
