NAMING BINARY IONIC COMPOUNDS
FOR METAL AND NONMETAL
How to name an ionic
compound formed by a metal Name: metal + nonmetal stem +
and nonmetal? ide
EXAMPLE OF NAMING IONIC
Can you give me an example of
COMPOUNDS FORMED BY
naming ionic compounds
METAL AND NONMETAL:
formed by metal and
nonmetal? KCL = Potassium + Chlorine + ide
For Chlorine, Remove ine and
change to ide
KCL = Potassium + Chlor + ide
Therefore, KCL (ionic
compound) is called Potassium
chloride.
REFLECTION
To name ionic compounds formed by metal and nonmetal. Name = metal +
nonmetal stem + ide.
, FOR TRANSITION METAL AND
NONMETAL
There are two ways to name ionic
compounds formed by transition
metals and nonmetals:
• New name
How to name an ionic Name:
compound formed by a transitional metal (with roman
transitional metal and numeral) + nonmetal stem + ide
nonmetal through the new
method? Note: The roman numeral
corresponds to the number of
valence electrons the nonmetal
has.
How to name an ionic • Old name
compound formed by a
Name:
transitional metal and
transitional metal stem + ous / ic
nonmetal through the old
+ nonmetal stem + ide
method?
Note: Use “Ous” if valence
electrons are 1-2+, while “Ic” if
valence electrons are 3-4+.
EXAMPLE OF NAMING IONIC
Can you give me an example of COMPOUNDS FORMED BY
naming ionic compounds TRANSITIONAL METAL AND
formed by transitional metal NONMETAL:
and nonmetal?
����3 = Iron + Chlorine + ide
Answer in New name:
Iron (I) chloride
REFLECTION
To name ionic compounds formed by transitional metal and nonmetal. Name
= transitional metal + nonmetal stem + ide.
For New naming of transitional metal and nonmetal, The roman numeral
corresponds to the number of valence electrons the nonmetal has.
