Bonding Flashcards
Define Ionic Bonding
Ionic Bonding is the Electrostatic Attraction between Oppositely Charged Ions
What is a Covalent Bond?
A Covalent Bond is a bond formed by a Shared Pair of Electrons
Do Ionic Compounds Have High or Low Melting/Boiling Points? Why?
Ionic Compounds have High Melting/Boiling Points because of Strong Electrostatic Forces of Attraction
When do Ionic Compounds Conduct? Why?
Ionic Compounds Conduct when Molten or in a Solution as Ions become Mobile can can Carry a Current
What Shape do Ionic Compounds Form?
Ionic Compounds form Giant Lattices
What does Expanding the Octet mean?
Some Elements use their Empty d Sub-Shells to Accept More Than 8 Electrons into their Outer Shell through Covalent Bonding
What does Reducing the Octet mean?
Reducing the Octet is where some elements can have Less than 8 Electrons in their Outer Shell through Covalent Bonding. They keep the Same Number of Outer Electrons and find Stability Through Other Means.
What Is A Lone Pair?
A Lone Pair is an Outer-Shell pair of Electrons Not involved in Chemical Bonding
What is a Dative Covalent Bond?
A Dative Covalent Bond is a Shared Pair of Electrons provided by only One Bonding Atom
Do Simple Covalent Molecules Conduct?
Simple Covalent Molecules Don’t Conduct
What Structure do Giant Covalent Substances have?
Giant Covalent substances form Large Lattice Structures
What Giant Covalent Molecule Can Conduct?
Graphite can Conduct
Define Metallic Bonding
Metallic Bonding is the Electrostatic Attraction between Positive Metal Ions and Delocalised Electrons
In Metallic Bonding, What Happens to the Melting/Boiling Points When There are More Electrons?
When there are More Electrons in Metallic Bonding, The Melting/Boiling Points Increase
Why are Metals good Conductors?
Metals are Good Conductors as Delocalised Electrons can Carry Charge
