GENERAL CHEMISTRY 1 - Chemical Formula and the ion with the lowest charge, while –ic indicates
Nomenclature (NERY, 11E) highest.
There are two types of ions in chemical substances:
Cations - positively-charged atoms or molecules
Cations formed from nonmetal atoms have the suffix
Anions - negatively-charged atoms or molecules –ium
** Cation - metal na nagkaroon ng charge There are only two of them
Anion- nonmetal na nagkaroon ng charge
• When positively-charged particles attract Rules in Naming Anions
negatively-charged particles, they can form ionic Monoatomic anions will have the suffix -ide
compounds.
- Positive charge + negative charge =
attraction > forming a bond called ionic bond
• Ionic compounds are usually named based on
their cation’s name followed by anion’s name. ** Difference ng cation at anion:
- Ionic compounds are composed of cations - Sa cation, kung anong name niya a periodic
and anions. table, yun na yun.
- Sa anion, madadagdagan pa siya ng suffix na
Ionic Compounds -ide.
Types of Ionic compounds Polyatomic anions with oxygens are called
1. Binary ionic compounds - ionic compounds oxyanions. They usually bear the suffix –ate for the
formed from just two elements and commonly ends common oxyanion, and –ite if is one oxygen less
with the suffix –ide than the common.
2. Ternary compounds - ionic compounds formed - Polyatomic: composed of many atoms
from a combination of more than two elements.
They have variety of suffixes other than -ide
Rules in Naming Cations
Cations formed from metal atoms bears the name of The following are the common oxyanions that you

Some metal ions can have more than one charge
such as those in the transition metals. We name Some oxyanions can be extended to form four
them as the name of the metal itself and a Roman members. We add prefix per- to the oxyanion with
numeral enclosed in parenthesis to indicate the one oxygen more than the common, and prefix hypo-

Usually, metals with two charges only can be named Anions derived by adding H^+ to an oxyanion are
using their root Latin name / old metal name followed named by adding as a prefix the word hydrogen/bi-
by the suffix –ous and –ic. The suffix –ous indicates or dihydrogen
