Binary Compounds

“The most mind blowing concept one could ever learn.” - N.S.

By AK, NS,And JK 2007

“-ide”

Binary compounds are distinguishable due to the “ide” at the end of the second element in

the name.

Binary Compounds:A compound with two elements

Type 1:“Ionic” (metal + non metal)Charged!

Type 2:“Covalent” (non metal + non metal)

Ionic Compounds

Metal + Non Metal

The total charge of all the atoms in an Ionic compoundmust equal…

0(zero)

For Example

With Water (H2O)

the Hydrogen has a charge of 1

the Oxygen has a charge of -2

1+1+-2=O

It takes two hydrogen atoms to cancel out the charge of the oxygen atom

Transition Metals

• Transition Metals can be found in the center of the periodic table.

• These elements can change their charges depending upon what they are paired with.

• These charges are noted in compounds with roman numerals.

For Example

The transition metal, lead, can have a charge of +4 or +2

With a charge of 2 when paired with oxygen the compound is written as lead(II) oxide.

Pb+2 and O-2 = PbO

Covalent Compounds

Nonmetal+Nonmetal

Covalent Compounds

• Elements do not develop charges within covalent compounds.

• You know how much of each element is in the compound based on the prefixes on the elements in the scientific name.

The Prefixes

• Mono - 1 (only on second element) • Di - 2• Tri - 3• Tetra - 4• Penta - 5• Hexa - 6• Hepta - 7• Octa - 8• Nona - 9• Deca - 10

For Example

• CO2

• CO

• C2O3

• Carbon Dioxide• Carbon Monoxide• Dicarbon Trioxide
