Naming Binary Compounds

Flashcards for naming binary compounds based on lecture notes.

Binary Compound

A chemical compound made of two different elements.

Element Order in Chemical Formula

The element that is more metallic or less electronegative is written first in the chemical formula.

Metallic Trend on Periodic Table

The metallic nature of elements increases as you move down and to the left on the periodic table.

Naming Convention for Second Element

The ending of the second element's name is changed to '-ide'.

Prefix Usage in Ionic Compounds

Ionic compounds do not use prefixes to indicate the number of atoms.

Prefix Usage in Covalent Compounds

Covalent compounds use prefixes to indicate the number of atoms.

Mono Prefix Rule

The prefix 'mono' is not used for the first element in a covalent compound.

Octet Rule

Main group elements tend to gain or lose electrons to achieve a noble gas electron configuration.

Charge of Common Ions

Elements in group 1 form +1 ions, group 2 form +2 ions, and aluminum forms +3 ions.

Common Anion Charges

Nitrogen forms -3 ions, oxygen forms -2 ions, and fluorine forms -1 ions.

Charge and Subscript Relationship

The magnitude of one ion's charge becomes the subscript of the other element in the chemical formula.

Ionic Compound Ratio Reduction

For ionic compounds only, reduce the ratio of ions to the smallest whole numbers.

Multivalent Ions

Metals that can form more than one stable ion.

Naming Multivalent Ionic Compounds

Multivalent ionic compounds are named using Roman numerals to indicate the charge of the metal.

Roman Numeral Meaning

The Roman numeral indicates the positive charge of the metal ion.
