Chapter 3/4 -- Ionic and Metallic Bonds

How do atoms gain or lose electrons?

How do atoms gain or lose electrons?

By bonding with other elements

How does bonding with elements occur?

Orbitals have to overlap, or electrons from other atoms must attract to other protons

What bond attracts any atoms?

Chemical bond

What makes an ionic bond?

Formed between metals and nonmetals

What is ion electron configuration?

As all atoms want to gain or lose electrons to aquire a noble gas configuration

Ionic bond

force of an attraction, attraction from ions

ionic compound

bonds by metal cation and non-metal anions

Properties of ionic compounds

Produces structures

contributes to bulk apperance

high melting and boiling points

conducts electricity as liquid

high melting and boiling points

brittle

rigid

Crystal Lattice

-+-

+-+

-+-

Very strong as they all repel and atract to eachother. In a good form, like this, theyre strong. Moved once down makes them brittle.

Metallic Bond

Only metals that are bonded

Where are electrons released in?

The Sea, which is a negative flow

What are the electrons that are released called from metallic bond?

Delocalized electrons

Why are transition metals harder in the center?

As you go more towards the metal, you gain more delocalized electrons, having a stronger attraction making it harder to seperate

What is an Alloy?

a mixture of metals. Does not change chemical property, changes physical. Takes off beneficial properties of both metals.

All ionic compounds are also called…
