Key Notes
When the metals in Groups 1A, 2A, and 3A lose electrons, they form cations with
What are positive charges equal to their group number?
Consist of a single atom with a positive or negative charge resulting from the loss or gain of one or more valence electrons.
What is Monatomic Ions?
A compound that produces hydrogen ions when dissolved in water.
What is Acid?
This ending generally indicates a binary compound
What is -ide?
Established the school.
Who are the Sisters of St.Joseph
The Charges of the cations of many transition metal ions must be determined from
What is the number of electrons lost?
Is composed of two elements.
What is Binary Compound?
A compound that produces hydroxide ions when dissolved in water
What is a Base?
This ending indicates a polyatomic ion that includes oxygen in the formula.
What is -ate

Who is Todd Declemente?
Unlike a monoatomic ion, a polyatomic ion is composed of more than one atom. But like a monatomic ion, a polyatomic ion behaves as a unit and
What is carries a charge?
Any charged particle, whether it is a positive or negative charge
What is an Ion?
States that in samples of any chemical compound, the masses of the elements are always in the same proportions
What is Law of definite proportions?
Tells how many atoms of an element are present in each molecule of a compound.
What is a Prefix?
The Chemistry teacher of SJA
To name any binary ionic compound, place the cation name first, followed by the
What is Anion name?
Any atom, or group of atoms with a positive charge
What is Cation?
States that whenever the same two elements form more than one compound, the different masses of one element, that combine with the same mass of the other element are in the ratio of small whole numbers
What is the Law of multiple proportions
How the positive charge of the metal is written in a compound.
What is a Roman Numeral?
To name a compound containing a polyatomic ion, state the cation name first and then the anion name. If the cation is a metallic element that has more than one common ionic charge, include a Roman numeral in the
What is Cation Names
Any atom, or group of atoms with a negative charge
What is Anion?
Composed of more than one atom
What are the Polyatomic Ions
