Unit 4 Bonds

Ionic bond is....

• Nonmetal + Metal

• Metals

• Non-metal + Non-metal

• Metal +Metal

Covalent Bond is...

• Nonmetal+metal

• metals

• Nonmetal + Nonmetal

• Metal + Metal

Metallic Bond is...

• Metal + Nonmetal

• nonmetals

• non-metal + non-metal

• Metal + Metal

Covalent Bonds require us to .....

• have elements floating in the sea of electrons

• use lines as bonds for single, double or triple bonds

• get the charges to equal out to zero

Ionic Bonds require us to ...

• have a sea of electrons

• use lines as bonds

• Get the overall charge equal to zero

Metallic bonds....

• Release & Gain Electrons

• Share electrons

• are bonds that are malleable , highly thermal, conduct electricity because of free moving electrons

Ionic Bonds form

• forms a sea of electrons

• crystal lattice based on electrostatic Attraction & Repulsion

• malleable

Metallic bonding...

• forms crystal lattice structures

• forms a sea of electrons

• is Not malleable

Electronegativity difference is large enough to cause unequal sharing of electrons but not large enough to cause a transfer of electrons from one atom to another

• ionic

• polar covalent

• non-polar covalent

• metallic

Answer explanation

A transfer of electrons describes ionic bonding. More electronegativity, means a big bully is present.

Bonded atoms share electrons without a dipole moment

• Ionic bonds

• polar covalent

• non-polar covalent

• metallic bonds
