Electrons are shared or exchanged between elements This is an
exothermic process (energy is released) Both elements are more
stable than they were before the bond formed (have 8 valence
electrons)
Slide 4
The atoms are separated into individual components Endothermic
process (takes an input of energy to do this) If I want to break up
anything, I need to input energy into the process!!!!
Slide 5
Slide 6
Slide 7
Bonds formed by the exchange of electrons between a metal and a
non-metal Metals give away valence electrons Non-Metals Take the
valence electrons Form strong bonds between elements, and strong
compounds Based upon the differences in electronegativity between
the elements
Slide 8
Combination of metal-non-metal Two components are required to
form any ionic compound 1. Cation 2. Anion
Slide 9
Have a positive charge Are metal elements Lose electrons Always
written first in the compound formula Ex: Sodium Chloride NaCl
Slide 10
Always are formed from the non-metal element Gain Electrons
Negative Charge Last in the compound formula and name Always have
an ide ending Ex: Sodium Chloride NaCl
Slide 11
Formed from a metal/non-metal Strong bonds High melting and
High Boiling Point due to bond strength Solids at room temperature
(crystalline) Dissolve in water (polar) Conduct a current when
dissolved in water but not when solid.
Slide 12
Formed by the exchange of electrons All elements have a noble
gas configuration when the bonding process is finished (8 valence
electrons)
