Ionic vs Covalent vs Hydrogen bonds vs Van der Waals
An ionic bond has _ polarity
high
A weak bond between two molecules results in an electrostatic attraction would be a
hydrogen bond
A covalent bond has _ polarity
low
When two metals bond it is a
metallic ionic bonding
An ionic bond has _ shape
no definite
Positive and positive
repel
Definition of Covalent bond
results from sharing of a pair of electrons due to an overlap of half filled orbitals
A hydrogen bond has _ polarity
super low
A bond between an acid and a base is
an ionic bond
Negative and positive
attract
Metals are usually what type of ion
cation
Definition of Ionic Bond
chemical bond formed when one or more electrons are transferred from one atom to another
A covalent bond has _ shape
definite
Van der waals use what instead of polarity?
dipoles
A covalent bond forms between what types of atoms
two non metals
Definition of hydrogen bond
A type of weak chemical bond formed when the slightly positive hydrogen atom of a polar covalent bond in one molecule is attracted to the slightly negative atom of a polar covalent bond in another molecule.
Non metals are usually what type of ion
Anion
How do geckos walk on walls?
Through van der waals
VESPR model
Valence shell electron pair repulsion (VSEPR) theory is a model used in chemistry to predict the geometry of individual molecules from the number of electron pairs surrounding their central atoms.
