C3 Bonding Flashcards
Metallic
Occurs in metal elements and metal alloys
And electrical conductivity is good in both solid and liquid
Ionic
Electrostatic attraction between oppositely charged ions
Occurs in compound containing metals and non-metals
Electrical conductivity in liquids and acquiesec is good and poor in solid
Covalent
Eleftrostatic attraction between a shared pair of electron and the nuclei of two atoms
Occurs in non-metal elements and compunds
Poor conductour
Giant metalic structure
All solid at room temperature (25) with HIGH melting points because lots of energy is required to break many strong bonds
Simple molecular and montanic
‘Soft’ solids,liquidor gases at room temperature(25) with LOW melting points and boiling points as not much energy is required to break weak intermolecular force between molecules
Iconic bond
The ionic bond is the electrostatic attraction between oppositely charged ions
What are positive ions called
Cations
Is the metal in group in group 1,2 or 3
Group 1-+
Group 2-2+
Group 3-3+
What does the numerical number mean
(I)-+
(II)-2+
(II)-3+
Is it amminium or hydrogen or acid
Ammonium=NH+4
Hydrogen or acid= H+
What are negative ions called
Anions
Is th non-metal in group 5,6 or 7 and the end of the name changed to IDE
Group 5=3-
Group 6=2-
Group 7=-
What are the polyotomic ions
Nitrate Sulfate Carbonate Hydrogencarbonate Hydroxide
Ionic bond
The electrostatic force between the positive and negative charged ions
What is a molecule
A molecule is a substance made up of non-metal atoms joined by covalent bonds
