Naming Ionic Compounds and Understanding Metallic Bonds

Cation

Positive ion formed by losing electrons.

Anion

Negative ion formed by gaining electrons.

Ionic Bond

Bond formed between cations and anions.

Polyatomic Ion

Cluster of two or more elements with a charge.

Binary Ionic Compound

Compound made of two elements.

Ternary Ionic Compound

Compound made of three or more atoms.

Variable Charge Metal

Metal that can have multiple oxidation states.

Roman Numeral Notation

Indicates charge of variable charge metals.

Metallic Bond

Bond between metal atoms sharing delocalized electrons.

Delocalized Electrons

Electrons not associated with a specific atom.

Alloy

Mixture of two or more metal atoms.

Substitutional Alloy

Alloy where metal atoms replace each other.

Interstitial Alloy

Alloy where smaller atoms fit between larger ones.

Malleability

Ability to be shaped into different forms.

Ductility

Ability to be stretched into wires.

Heat Capacity

Naming Anions

Change element name ending to 'ide'.

Naming Cations

Use metal name or polyatomic ion name.
