Chapter 1 Matter Matter is anything that has mass and takes up space. Section 2 Matter and Its Properties Chapter 1 Matter Matter is anything that has mass and takes up space. Volume is the amount of space an object occupies. Mass is a measure of the amount of matter.

Basic Building Blocks of Matter Section 2 Matter and Its Properties Chapter 1 Basic Building Blocks of Matter Atom- smallest unit of an element that maintains the chemical identity of that element. Element -pure substance made of one type of atom. Compound pure substance which has more than one element chemically combined

Chapter 1 Physical Properties Section 2 Matter and Its Properties Chapter 1 Physical Properties can be observed or measured without changing the identity of the substance melting & boiling point, color, mass, density

Intensive Properties -do not depend on the amount of matter present. melting point boiling point density ability to conduct electricity ability to transfer energy as heat

the amount of energy in a substance. Extensive properties -depend on the amount of matter that is present. volume mass the amount of energy in a substance.

Chapter 1 Chemical Properties Section 2 Matter and Its Properties Chapter 1 Chemical Properties Describes substance’s ability to undergo changes Ex. Reaction with acid or air

Chapter 1 Physical Changes Section 2 Matter and Its Properties Chapter 1 Physical Changes change in a substance that does not involve a change in the identity of the substance grinding, cutting, melting, and boiling change of state -physical change of a substance from one state to another.

Burning, tarnishing, digesting Chemical Change One or more substance becomes a new substance with different properties Burning, tarnishing, digesting

Chapter 1 Chemical Changes Section 2 Matter and Its Properties Chapter 1 Chemical Changes reactants -substances that react in a chemical change. products -substances that are formed Carbon plus oxygen yields (or forms) carbon dioxide. reactants product carbon + oxygen carbon dioxide

Section 3 Elements Chapter 1 Objectives Use a periodic table to name elements, given their symbols. Use a periodic table to write the symbols of elements, given their names. Describe the arrangement of the periodic table. List the characteristics that distinguish metals, nonmetals, and metalloids.

Regions of the Periodic Table Section 3 Elements Chapter 1 Regions of the Periodic Table

Introduction to the Periodic Table Section 3 Elements Chapter 1 Introduction to the Periodic Table The vertical columns of the periodic table are called groups, or families. The horizontal rows of elements in the periodic table are called periods.

Chapter 1 Types of Elements Metals Properties Section 3 Elements Chapter 1 Types of Elements Metals Properties most are solids at room temperature malleable - they can be hammered or rolled into thin sheets ductile - they can be drawn into a fine wire conduct electricity and heat well

Chapter 1 Types of Elements Gold, copper, and aluminum are metals Section 3 Elements Chapter 1 Types of Elements Gold, copper, and aluminum are metals

Chapter 1 Types of Elements Nonmetals Properties many are gases Section 3 Elements Chapter 1 Types of Elements Nonmetals Properties many are gases solids are brittle poor conductors of heat and electricity

Chapter 1 Types of Elements Various nonmetal elements Section 3 Elements Chapter 1 Types of Elements Various nonmetal elements (a) carbon, (b) sulfur, (c) phosphorus, and (d) iodine

Chapter 1 Types of Elements Metalloids Section 3 Elements Chapter 1 Types of Elements Metalloids element that has some characteristics of metals and some characteristics of nonmetals. Properties all metalloids are solids at room temperature semiconductors of electricity

Chapter 1 Types of Elements Noble Gases Section 3 Elements Chapter 1 Types of Elements Noble Gases elements in Group 18 of the periodic table generally unreactive gases at room temperature
