Bonding
a chemical bond that involves the sharing of electrons to form electron pairs between atoms
covalent bond
one-half the distance between the nuclei of two atoms of the same element
atomic radius
the model that shows all the electrons in circular orbits around the nucleus
Bohr model
the VSEPR model is used in chemistry to predict the geometry of what
individual molecules
IMFs are the force that mediates interaction between what
molecules
in an ionic bond, a metal transfers one or more electrons to what type of metal?
a nonmetal
the measure of how well an element attracts electrons
electronegativity
in a Bohr model, what moves in circular orbits around the nucleus
all the electrons
how many electron pairs does a VSEPR diagram with a tetrahedral shape have
a special type of dipole-dipole force that is really strong
hydrogen bond
an ionic bond with a positive charge
cation
the difference between the electronegativity of different elements decides how they do what
bond
in a lewis dot structure, the diagram focuses on what within a molecule
valence electrons
when a VSEPR model has 2 electron pairs, what is the bond shape
linear
a type of IMF with a temporary attractive force (weak)
london dispersion force
a group of metal atoms of the same element, resulting in metallic bonding
sea of valence electrons
as you go down the periodic table, what determines the protons getting farther from the electrons
valence shells
1
what does VSEPR stand for
valence shell electron pair repulsion
a dipole-dipole has attractive forces between the positive and negative ends of what type of molecules
polar molecules
the type of covalent bond when electrons are more unequally shared between the atoms
polar covalent bond
as you move from left to right of the periodic table, the increase in what pulls its electrons closer together
protons
a diagram that focuses on representing the valence electrons of atoms within a molecule
lewis dot structure
what is the bond angle of a VSEPR diagram with an octahedral shape
90 degrees
what does IMFs stand for
intermolecular forces
