Interatomic Bonding Flashcards
(11 cards)
What are the ranges of electronegativitues on the periodic table
0.7 - 4.0
What are the characteristics of ionic bonds
Requires electron transfer
Large diff. In electronegativity
Happens between positive and negative ions
Usually between a metal and non metal
Non directional
What are the primary bonds
Ionic
Covalent
Metallic
T/F primary bonds either transfer or share electrons
True
What occurs in bond hybridization
Orbital overlap and some electrons are temporarily promoted
What is the main type of secondary bond and what are its characteristics
Van der waals and it usually has a asymmetrical distribution of electrons.
What are the characteristics of covalent bonds
It occurs between elements with similar electronegativies, in valves valence electrons, and orbital overlap.
What are the characteristics of metallic bonds
Electrons form and electron sea that acts as glue for the ion cores.
What are the two types of dipoles
Fluctuating and permanent
What is Van der waals bonding
It is the interaction between atomic or molecular dipoles
What is a hydrogen bond
When H is covalently bonded with a highly electronegative element.
