Ionic Bonds characteristics +Covalent + Network Bonds

Ionic bonds create…

ionic compounds or “salts”

Ex: NaCl

Ionic bonds are between…

metals + nonmetals or a metal + polyatomic ion

Ionic bonds are formed when there is a transfer of..

electrons, forming a positive and negative ion.

What type of attraction is between positive and negative ions?

Electrostatic Attraction (Opposites attract).

The Electronegativity difference is greater than..

1.7 (referred as Ionic character).

What type of bonds do crystal lattices have in Ionic bonds?

Strong bond.

What is high in Ionic bonds?

High melting and boiling points.

Ionic Bonds are mostly soluble (can dissolve) in…

water (molecule-ion attraction).

Ionic bonds conduct…

electricity when melted (molten) or dissolved in water (aq).

Ionic bonds have strong…

bonds and electrolytes.

What state is the crystalline lattice structure in?

Solid state.

Empirical Formula:

2:2 ratio can be simplified and divided by 2, creating 1:1. You can’t reduce the subscripts anymore.

Crystal Lattice:

Organization of atoms for stability (8).

Transition metals have…

multiple ions.

Binary Ionic Bonds:

2 elements

Polyatomic ions are not…

Binary.

Empirical example:

N2O5 (You cannot reduce it anymore).

Network Bonds are…

covalent (share electrons)

Network Bonds are bonded in a large…

crystal

Network Bonds are strong and have…

high melting and boiling points.

Network Bonds examples:

SiC (Quartz)

SiO2 (Sand)

C (Diamond)

Metallic Bonds have…

Free mobile/moving electrons.

Metallic Bonds are good…

conductors of heat/electricity.

Metallic Bonds characteristics…

Ductile (Metals are pulled by a wire), and Malleable (can be hammered into thin sheets).

Metallic Bonds examples:

Na, Au, Ag (Any metal).
