Structure of Matter• Analyze what makes up matter• Compare the different models of an atom.

Structure of MatterDefine matter

anything that has _________ and takes up space

mass

Structure of MatterWhat is matter?

air is matter water is matter most of the things you see, taste, smell, and touch are made of matter

Structure of MatterWhat isn’t matter?

light heat thoughts, feelings, ideas

these things have no mass, nor do they take up space

Structure of MatterWhat makes up matter? atoms

Structure of MatterDefine atom

a particle that makes up most types of ___________matter

Structure of MatterCan matter be made or destroyed?

matter is not _________ nor ___________, it just changes into a different form this is the law of conservation of matter

createddestroyed

Before Lavoisier, people used to think _________ could appear and disappear.

Structure of Matter

matter

Structure of MatterWhat was Dalton’s model of an atom?

the atomic theory of matter: each type of matter was made of only _________ of atom

one kind

Structure of MatterHow small is an atom?

1 million lined up in a row would be as thick as a human hair

(too small to be seen by a classroom microscope)

Structure of MatterWhat is an electron?

invisible particles of an atom with negative charges

Structure of MatterWhat was Thomson’s model of an atom?

Thomson thought an atom was a ball of ______________ with negatively charged electrons in it

positive charges

Structure of MatterWhat was Rutherford’s model of an atom?

Rutherford’s model included a ________ with protons inside and electrons around the nucleus

nucleus

Structure of MatterDefine nucleus

positively charged, central part of an atom

Structure of MatterDefine proton

___________ charged particles in the nucleus of an atom

positively

Structure of MatterHow was the neutron discovered?

James Chadwick, a student of Rutherford, discovered neutral particles that gave the nucleus more mass

Structure of MatterDefine neutron

neutral particle in the nucleus of an atom

Structure of MatterWhat was Bohr’s model of an atom?

Bohr’s model indicated that electrons traveled in paths around the nucleus

(lowest energy levels closest to the nucleus)

Structure of MatterModern Atomic Model

Electrons travel in an electron cloud rather than in paths
