Transcription:

Ionic Bonding attracted Covalent Bonding fully,to each other but not fully committed and shares. committed everything,Two methods to gain or lose valence electrons. Transfer of Electrons Ionic Bonding,Sharing of Electrons Covalent Bonding. Naming Covalent Compounds, Prefixes used to denote number of atoms of element. Numerical Prefixes,mono 1 hexa 6,di 2 hepta 7,tri 3 octa 8.
tetra 4 nona 9,penta 5 deca 10, The suffix ide is added to the more electronegative. For the least electronegative on the left mono is not. used to denote one atom,Molecule covalently bonded atoms. Diatomic molecule two atoms,Molecular compounds lower melting and. boiling point than ionic compounds,Molecular formula. Doesn t have to be lowest whole number ratio,Does represent structure.
Molecular Representations,Figure 8 5 Pg 215 Text,Lewis dot structures of covalent. In covalent compounds atoms share electrons,We can use Lewis structures to help visualize. the molecules,Lewis structures,Multiple bonds must be considered. Will help determine molecular geometry,Will help explain polyatomic ions. Types of electrons,Bonding pairs,Two electrons that are shared between two.
atoms A covalent bond,Unshared pairs,A pair of electrons that are not shared. between two atoms Lone pairs or nonbonding,electrons Unshared. Bonding pair Chapter 8,Single covalent bonds,H H H C H F F. Do atoms except H have octets,Covalent Bonding,When two similar atoms bond. none of them wants to lose or,gain electrons,Share pairs of electrons to each.
obtain noble gas e,configuration,Each pair of shared electrons. Visual Pg 219 Text,one covalent bond,Unshared Pairs Pairs of e. not shared by all atoms N,Show unshared pairs as dots H H. Sharing of Electrons,Water H2O Covalent,Each H shares their electron. with O O 8e Ne,O shares 1e with each H Visual Pg 218 Text.
Use dashes or dots to show,covalent bonds,Multiple Covalent Bonds. Elements can share more,than two electrons creates. double and triple bonds,Carbon Dioxide CO2 4,electrons shared between the. carbon and the oxygens,double bond,Triple Covalent Bonds. Triple bond Six electrons shared between the,carbon atoms.
Ethyne C2H2 a k a acetylene,H C C H H C C H,Bond length decreases from single to triple bonds. Bond strength increases from single to triple bonds. Coordinate Covalent Bonds,Coordinate covalent bond one atom. contributes both bonding electrons,O must contribute one of its pairs. Polyatomic ions contain coordinate covalent,Resonance Structures. Structures with multiple bonds can have similar, structures with the multiple bonds between different pairs.
of atoms Resonance Structures,Example Ozone has two identical bonds whereas the. Lewis Structure requires one single longer and one. double bond shorter,Resonance Structures,Resonance Structures. Chapter 8 Covalent Bonding When two similar atoms bond none of them wants to lose or gain electrons Share pairs of electrons to each obtain noble gas e configuration Each pair of shared electrons one covalent bond Unshared Pairs Pairs of e not shared by all atoms Show unshared pairs as dots Visual Pg 219 Text N H H H Chapter 8 Sharing of Electrons Water H 2 O
