Define Ionic Compounds

Formed when atoms transpher electrons

Define Covalent Compounds

Formed when electrons are shared

Define Binary Ionic Compounds

Made from 1 type of metal and 1 type of nonmetal

Define Ternary Ionic Compounds

Made from 1 metal and 1 type of Polyatom (multiple nonmetals)

Define polyatom

Multiple nonmetal atoms bonded

Define Bonding Pair of Electrons 

The pair of VE electrons shared between atoms 

Define Lone pair of Electrons

The lone pair of VE on an atoms that is not paired with another atom

Properties of a Ionic compound are…(Attraction, melting/boiling pt.,phase at room temp., electoral conductor)

Very strong force of attraction, High melting point, typically solid at room temp., are electoral conductor.

Properties of a Covalent compound are….(Attraction, melting/boiling pt.,phase at room temp., electoral conductor)

Force of attraction is weaker then ionic compound, low melting/ boiling pot., phase at room temp. is liquid or gas, is not an electrical conductor)

Define Electrolyte

Substance that conducts electricity

What compound transfers electrons?

Ionic Compounds

What compound has Electrolyte melted or dissolve in water?

Ionic compound 

Define Chemical formula?

Consist of element symbol and subscript.

Ionic Compounds are electrically (__) overall? ( Fill in blank)

Electrically (Neutral)

When naming Binary Ionic compound what do I put on the last few letters of the nonmetal element?

-ide

Transition Metal Ionic Compound is….

A metal that has more than one possible Ionic charge (orange/ middle chunk)

What two element are considered transition metals when naming (Romain numerals) Ionic compounds?

Sn & Pb

(____) are used in the NAMES of Ionic Compounds with transition metals and Sn & Pb to denote the charge of the metal?

(Roman Numerals)

What three elements always DO NOT have Roman Numerals?

Zn (Zinc +2), Ag (Silver+1), Cd (Cadmium+2)
