3 The Structure of Atoms Learning Objective 2-1 Describe the structure of an atom and its relation to the physical properties of elements.

4 The Structure of Atoms Chemistry is the study of interactions between atoms and molecules The atom is the smallest unit of matter and cannot be subdivided into smaller substances Atoms interact to form molecules

5 The Structure of Atoms Atoms are composed of Electrons: negatively charged particles Protons: positively charged particles Neutrons: uncharged particles

6 The Structure of Atoms Protons and neutrons make up the nucleus Electrons move around the nucleus

7 Figure 2.1 The structure of an atom. Electron shells Nucleus Proton (p + ) Neutron (n 0 ) Electron (e )

8 Chemical Elements Atoms with the same number of protons are classified as the same chemical element Each different chemical element has a different number of protons Atomic number: number of protons in the nucleus

9 Chemical Elements Atomic weight is the total number of protons and neutrons in an atom Isotopes of an element are atoms with different numbers of neutrons Isotopes of oxygen: 16 O 17 O 18 O 8 8 8

10 Table 2.1 The Elements of Life*

11 Electronic Configurations Electrons are arranged in electron shells corresponding to different energy levels

12 Check Your Understanding ü How does 14 C differ from? What is the atomic 6 6 number of each carbon atom? The atomic weight? C

13 How Atoms Form Molecules: Chemical Bonds Learning Objective 2-2 Define ionic bond, covalent bond, hydrogen bond, molecular weight, and mole.

14 How Atoms Form Molecules: Chemical Bonds Atoms form molecules by combining to fill their outermost shells The number of missing or extra electrons in the outermost shell is known as the valence Molecules hold together because the valence electrons of the combining atoms form attractive forces, called chemical bonds, between the atomic nuclei

15 How Atoms Form Molecules: Chemical Bonds A compound is a molecule that contains two or more kinds of atoms Water: two atoms of hydrogen, one atom of oxygen H 2 O

16 Ionic Bonds The number of protons and electrons are equal in an atom Ions are charged atoms that have gained or lost electrons

17 Figure 2.2a Ionic bond formation. Loss of electron Gain of electron Sodium atom (electron donor) Sodium ion (Na + ) Chlorine atom (electron acceptor) Chloride ion (Cl ) A sodium atom (Na) loses one electron to an electron acceptor and forms a sodium ion (Na + ). A chlorine atom (Cl) accepts one electron from an electron donor to become a chloride ion (Cl ).

18 Ionic Bonds Cations are atoms that lose electrons and become positively charged ions Anions are atoms that gain electrons and become negatively charged ions

19 Ionic Bonds Ionic bonds are attractions between ions of opposite charge One atom loses electrons, and another gains electrons

20 Figure 2.2b Ionic bond formation. Sodium ion (Na + ) Chloride ion (Cl ) Sodium chloride molecule Na + Cl NaCl The sodium and chloride ions are attracted because of their opposite charges and are held together by an ionic bond to form a molecule of sodium chloride.

21 Covalent Bonds Covalent bonds form when two atoms share one or more pairs of electrons Covalent bonds are stronger and more common in organisms than ionic bonds

22 Figure 2.3a Covalent bond formation.

23 Figure 2.3b Covalent bond formation.

24 Hydrogen Bonds Hydrogen bonds form when a hydrogen atom that is covalently bonded to an O or N atom is attracted to another N or O atom in another molecule

25 Figure 2.4b Hydrogen bond formation in water. Hydrogen bond

26 Molecular Weight and Moles The sum of the atomic weights in a molecule is the molecular weight One mole of a substance is its molecular weight in grams H 2 O 2H = 2 1 = 2 O = 16 MW = 18 1 mole weighs 18 g

27 Check Your Understanding ü Differentiate an ionic bond from a covalent bond. 2-2

28 Chemical Reactions Learning Objective 2-3 Diagram three basic types of chemical reactions.

29 Chemical Reactions Chemical reactions involve the making or breaking of bonds between atoms A change in chemical energy occurs during a chemical reaction Endergonic reactions absorb energy Exergonic reactions release energy

30 Synthesis Reactions Occur when atoms, ions, or molecules combine to form new, larger molecules Anabolism is the synthesis of molecules in a cell

31 Decomposition Reactions Occur when a molecule is split into smaller molecules, ions, or atoms Catabolism are decomposition reactions in a cell

32 Exchange Reactions Are part synthesis and part decomposition

33 The Reversibility of Chemical Reactions Can readily go in either direction Each direction may need special conditions

34 Check Your Understanding ü This chemical reaction below is used to remove chlorine from water. What type of reaction is it? 2-3 HClO + Na 2 SO 3 Na 2 SO 4 + HCl

46 Figure 2.6c Acids, bases, and salts.

47 Acid-Base Balance: The Concept of ph The concentration of H + in a solution is expressed as ph ph = log 10 [H + ] Increasing [H + ] increases acidity Increasing [OH ] increases alkalinity Most organisms grow best between ph 6.5 and 8.5

48 Figure 2.7 The ph scale. ph scale 0 H + OH Acidic solution Increasingly ACIDIC Stomach acid Lemon juice Grapefruit juice Wine Tomato juice 6 Urine NEUTRAL [H + ] = [OH ] 7 Milk Pure water Human blood 8 Seawater Neutral solution Increasingly BASIC Milk of magnesia Household ammonia Household bleach 13 Oven cleaner Basic solution 14 Limewater
