This document discusses ionic bonding, which occurs when atoms gain or lose electrons to achieve stable full outer electron shells of eight electrons. Metals tend to form cations by losing electrons, becoming positively charged ions. Nonmetals tend to form anions by gaining electrons, becoming negatively charged ions. Ionic bonds form when these opposite ions are attracted to each other, such as between sodium and chloride ions to form sodium chloride or table salt.

2.  Octet rule - _____8 electrons in the outer shell.
 atoms tend to gain, lose or share electrons to
try and have eight electrons in their outer shell.
 Noble gases are non-reactive because they
have 8 valence electrons.

3. IONIC
BONDING

4. •Its all about “I”
•Bonding by gaining or losing electrons to
achieve a full outer shell

5. Electrons in the outer most
shell
We use these to help with bonding

6.  Ion – charged atom (atom that has gained/lost
electron and has a positive or negative charge)
 Cation – ion with positive charge
 Anion – ion with negative charge

7.  An ion is a atom that has gained or lost
one or more electrons and has a positive or
negative charge.
 Atoms gain or lose electrons in order to
achieve the octet rule (8 valence electrons)

8.  NOTE – when you see a (+), the atom is
LOSING an electron.
 NOTE – when you see a (-), the atom is
GAINING an electron

9.  Metals
 Nonmetals
 Metalloids

10.  Nearly all metals form cations.
 Mg has 2 valence electrons. It is much easier to
lose two electrons than gain six electrons.
 Mg 2+ …..cation

11.  Nearly all nonmetal elements form anions.
 Oxygen has 6 valence electrons
 It is much easier for Oxygen to gain two
electrons than to lose six.
 O 2- ……..anion

12.  Naming a Cation (positive ions, atoms
that lose electrons)
 Simply the name of the element
 Example: Na+ - sodium ion
Mg 2+ - Magnesium ion

13.  Naming an Anion – (negative ions,
atoms that gains electrons)
 The element name ends in –ide.
 Example: Cl- - chloride ion
O2- - oxide ion

14.  The force of attraction between a positive
charge and negative charge creates the ionic
bond.
 Ex: Wants to be neutral…Sodium ion (Na+)
has a +1 charge and Chloride ion (Cl-) has a -1
charge.
 Sodium Chloride…table salt

16. IONIC bond -
electrons are lost or gained,
resulting in the formation of IONS
