classification of matter
Everything that has mass and volume.
Matter.
What particles form the nucleus of atoms?
Protons and Neutrons
A salad, sand, and blood are all examples of this type of mixtures.
Heterogeneous.
Ion.
Mass, Volume and Length are examples of these properties.
Extensive.
combination of two or more substances.
Mixture.
where are the electrons located in an atom?
Mixture separation method used to separate two dissolved liquids utilizing different boiling points of each substance.
Distillation.
What is Avogadro’s number?
6.022x10-23
Properties of matter that do not depend on the amount of substance.
Intensive.
Pure substance made of one type of atom.
Element.
What is the atomic mass of an atom?
The sum of its protons, neutrons and electrons.
Type of mixtures where its phases have combined to form a single visible phase.
Homogeneous.
what makes every atom (element) unique?
Its number of protons.
The change in coloration and formation of rust in a wet iron nail means that this type of change took place.
Chemical change.
Substances made of two or more elements.
Compound.
What is the atomic number?
Number that identifies the atom based on its number of protons.
Mixture separation method that utilizes a change of phase to separate a dissolved solid in a liquid. Like salt from water.
Vaporization.
Type of atoms with a different number of neutrons than protons in its nucleus.
Isotope.
A sweater shrinking when hot dried is an example of this type of change.
