Basic Bonding Flashcards
The more energy released
The more stable a bond is
Metallic Bonds
few valence electrons low ionization energies
Metallic Bonds have a central portion or a
kernal (Crystalline lattice): Valence electrons float in the kernal, “Sea of electrons.”
Chemical bonds occur when
the attractive forces are greater than the repulsive forces
Covalent
Non metal + Non metal
Ionic
Metal + Non Metal
Polar electron distrubution
Not equal
Non polar electron distribution
Equal
Ionic electron distribution
Electrons are transferred
Ionic bonds occur when _______ and tend to result in ________
Two ions bond together
Full octets
Metals tend to
Lose electrons and become positive.
Non metals tend to
Gain electrons and become negative
Bonding is a
Exothermic process : energy is released
Breaking a chemical bond is a
Endothermic process : energy is absorbed/added
