Matter & Energy Ch. 1 Outline
1.1 Matter has mass and volume. A.Matter – anything that has mass and takes up space B.Mass – the amount of matter in an object C.Weight – the downward pull of gravity on an object
1.1 Continued D.Volume – the amount of space an object takes up E.Examples of matter – F.Examples of non-matter –
1.2 Matter is made of atoms. A.Atom – smallest basic unit of matter 1.Subatomic particles – smaller particles that make up an atom; protons, neutrons, and electrons 2.Nucleus – the center of the atom; contains protons and neutrons
1.2 Continued 3.Proton – a positively charged particle found in the nucleus 4.Neutron – a particle found in the nucleus that has no charge 5.Electron – a negatively charged particle found outside the nucleus
1.2 Continued 6. Drawing of an atom –
1.2 Continued B. Molecule – when two or more atoms combine together 1. A molecule can be made by combining alike or different atoms. 2. A molecule is the smallest amount of a substance made of combined atoms that is considered to be that substance.
Section 1.3 A.Pure substance – has only one type of substance B.Element – substance that contains only a single type of atom C.Periodic table – organized list of the elements 1.Mendeleev and Moseley were the two scientists who were involved in creating the modern periodic table.
1.3 Continued 2.Chemical Symbol – shorthand way of representing the elements; only one or two letters 3.Atomic number – number of protons D.Compound – substance that consists of two or more different types of atoms bonded together
1.3 Continued E.Mixture – combination of different substances that remain the same individual substances 1. heterogeneous – have different properties in different areas 2.homogeneous – evenly distributed; the same throughout
1.3 Continued MixtureCompound Substances Remain the same New substance formed Separation By physical means Breaking bonds ProportionsVaryFixed
