Inorganic Flashcards
Atoms of the same element that have the same
number of protons and electrons but different
numbers of neutrons are called .
isotopes
can be
produced from heavier elements.
Artificial isotopes, also known as radioisotopes,
isotopes are highly unstable such that when
they decay, they release enormous amounts of
radioactivity which can be harnessed to power up large
scale processes in nuclear reactors.
Artificial isotopes, also known as radioisotopes,
Smoke detectors
Americium 241
Detection of explosive
Californium
Treatment of thyroid disease
Iodine

are
charged particles formed when atoms lose or gain
electrons.
ions
are neutral entities.
Atoms
are neutral entities.
Atoms
is formed when an atom loses one or
more electrons resulting in a net positive charge.
cation
is formed when an atom gains one or
more electrons resulting in a net negative charge.
anion
compounds that are made of cations and anions
assembled together in a crystal lattice
Ionic Compounds
The bond that holds these ions together in the
lattice is called the
ionic bond.
are formed when there is an electron
transfer between two or more atoms.
Ionic bonds
The most Compounds important consideration in writing the
chemical formulas of ionic compounds is their
electrical neutrality.
When a cation and an anion combine, they must
form an ionic compound with a net charge of
.
zero
that are composed of
monatomic ions are called binary compounds.
Ionic compounds
You can use the _______ in writing the
chemical formula of ionic compounds.
criss-cross method
In writing the chemical formula of a compound, there are
few methods to consider, namely
Traditional or Stack Method
Roman Numerals
Latin Greek prefixes
(for metals with two or
more charges) – this method utilizes the ending
Traditional or Stack Method
which means that the higher charge is used
“ic”
Which means the lower charge is used
“ous”
uses
to represent the charge of the metal. This method is a
little bit easier to use than the traditional method since
the charge of the metal is already given. Looking at the
example given below, it can be written as
Roman numerals
like the one given below
this method is much easier than the first two methods
since one can still identify the chemical formula of a
compound even without identifying the charges.
