What is a bond? 4 Types of bonds Naming type I, II, & III

Overview

Page 3: Bonding and Naming Review

A bond is an electrostatic force that holds atoms together.

Atoms will bond using their electrons.

What is a bond?

Page 4: Bonding and Naming Review

Ionic bonding◦ Electrons are transferred from one atom to the

other. (give/take)◦ Happens between metals & nonmetals (cations &

anions).◦ The atom that loses the electron becomes positive

(cation) and the atom that gains the electron becomes negative (anion). . .ions, get it, ionic bond.

◦ Why does this happen? The electrogegativity difference between the atoms is > 1.7 so one atom is able to rip the electron away.

◦ Form a crystal lattice structure.

Types of Bonds

Page 5: Bonding and Naming Review

Covalent Bonding◦ Electrons are shared between atoms.◦ Happens between nonmetals only.◦ There are 2 types of covalent bonding based on

the amount of sharing of electrons. Polar covalent is uneven sharing, thus creating a

pole. Bond electronegativity difference <1.7 Structure asymmetrical.

Nonpolar covalent is even sharing, thus no pole. Bond electronegativity difference <0.4 Structure symmetrical.

Types of Bonding

Page 6: Bonding and Naming Review

Metallic bonding◦ Delocalized electrons float around the electron

sea.◦ Happens between metals only.◦ Characteristics:

Malleable Ductile Luster Conductor

Types of Bonding

A for ionic, B for covalent, and C for metallic◦ Li2S◦ AuAg◦ PbNO3◦ NO◦ C6H12O6◦ SnN

Identify the type of bond

A for ionic, B for polar covalent, C for nonpolar covalent◦ K2O◦NS3

◦N2◦AuI◦NaF◦C6H12

Identify the type of bond

Page 9: Bonding and Naming Review

Type I◦ Use for ionic bonds when the cation has only one

charge (groups1A-3A).◦ The first element keeps its name and the second

element changes the end of its name to –ide (unless it already has a fancy name).

◦ Criss-cross charges if uneven. Ex. NaBr is sodium bromide Ex. CaCl2 is calcium chloride Ex. Be(ClO3)2 is beryllium chlorate

Nomenclature (Naming)

Page 10: Bonding and Naming Review

Type II◦Use for ionic bonds when the cation has more

than one charge (transition metals).◦The first element keeps its name and the second

element changes the end of its name to –ide (unless it already has a fancy name).

◦Use a roman numeral to show the charge of the first ion.

◦Criss-cross charges if uneven. Ex. AuI is gold (I) iodide Ex. Mn2O3 is manganese (III) oxide Ex. W3(PO4)2 is tungsten (II) phosphate

Nomenclature

Page 11: Bonding and Naming Review

Type III◦ Use for covalent bonds.◦ Use prefixes to denote the number of atoms and

change the ending of the second element to -ide. Ex. S2O3 is disulfur trioxide Ex.N3P4 is trinitrogen tetraphosphide Ex. BrH5 is bromine pentahydride
