Transcript of Ionic & Covalent Bonding

POSITIVES
will be attracted to
NEGATIVES
.

The force of the attraction between a
Positively
Charged

Ion
and a
Negatively

Charged

Ion
is called and

Ionic Bond

Positive

Ion
is called a

Terms to Remember
Valence Electron
Ion=
a
Charged
atom in which the number of
ELECTRONS (-)
is different from the number of
PROTONS (+).

Ionic Charge=
is the number of
positive (+)
or
negative (-)
Charges
on an atom.

Na
&
Cl
Sodium is highly reactive and toxic.
In terms of electrons, what does sodium want to do?
So what would the charge be?
Chlorine Gas is poisonous
In terms of electrons, what does chlorine want to do?
So what would the charge be?
...
What would happen if we put

Na

and

Cl

together?
We get NaCl... A.K.A
SALT
Na
Cl
So what actually happened?
Sodium (Na) gave up its
valence
electron
to Chlorine (Cl)

Why do you think they are written together? Why are there no charges?

When two

Ions
Bond,
they form an

Ionic Compounds.

Negative

Ion
is called an

ANION
Ex. Mg
+2
Ex. NaCl
Ionic Compounds
are made up of
metals
and
non-metals
The
cation
is always written first, and the
anion
second
Notice the cross over of charges

Naming
Ionic Compound
Regular Names:

Write the name of the
metal
first
Replace the ending of the non-metal with
-ide
Ex. Calcium Chloride
Ca
Cl
Now it's your turn...
Create the chemical formula and the visual representation of the following Ionic Compounds. In addition give them proper names
Magnesium + Oxygen

Potassium + Fluorine

Calcium + Chlorine
Ex. When
Na
loses an electron it becomes a positively charges Ion= CATION

Na
+1
Ex. When
Cl
loses an electron, it becomes a negatively charged ion= ANION
Cl
-1
Side Note
Metals

are usually
cations
Nonmetals
are usually
anions
Two components of an Ionic Compound
Superscript
becomes the
Subscript
for the other
ion

NOTE: The element that is MOST METAL like goes first in the chemical formula and the name

Molecular & Diatomic
Compounds
Steps to Naming Molecular Compounds
Step 1:
Write how many of each atom you have
Step 2:
Write the correct prefix (ex. di, tri...etc) if necessary in front of the first element
Step 3:
Write the prefix of the next element, and continue to add
-ide
on the end
Naming Molecular Compounds
Name of the 1st element
Name of the 2nd element
