Intro to Chemical Bonding
What is "chemical bond"
What is "a neutral group of atoms that are held together by covalent bonds"?
What is a "molecule"
What is an ionic compound?
"a compound composed of positive and negative ions that are combined so that the numbers of positive and negative charges are equal"
What is metallic bonding?
"the chemical bonding that results from the attraction between metal atoms and the surrounding sea of electrons."
What is molecular geometry?
The 3D arrangement of a molecule's atoms in space
What is "chemical bonding that results from the sharing of electron pairs between two atoms"?
What is "covalent bond"
What is "a covalent bond in which the bonding electrons are shared unevenly"?
polar covalent
What is the difference between ionic and covalent bonds?
in ionic, the electrons are "transferred" while in covalent bonds, they are "shared."
What term is used to describe "the ability of a substance to be hammered or beaten into thin sheets"?
malleability
What two-word term describes an uneven distribution of charge across a molecule?
molecular polarity
What is "chemical bonding that results from the electrical attraction between cations and anions"?
What is "ionic bond"
What is "a covalent bond in which the bonding electrons are shared equally by the bonded atoms, resulting in a balanced distribution of electrical charge?"
non-polar covalent
What is the term that describes "the energy released when one mole of an ionic crystalline compound is formed from gaseous ions"?
What term is used to describe "the ability of a substance to be be drawn, pulled, or extruded through a small opening to produce a wire"?
Ductility
What is VSEPR theory?
"repulsion between the sets of valence level electrons surrounding an atom causes these sets to be oriented as far apart as possible."
What kind of bonding is in a polar molecule?
covalent (polar)
What is a "single covalent bond"?
a covalent bond in which ONE PAIR of electrons is shared between two atoms.
What is the two-word term used to describe "the simplest collection of atoms from which an ionic compounds formula can be established"?
formula unit
What structure do metallic bonds form?
Crystal lattice
What does VSEPR stand for?
valence shell, electron-pair repulsion
What is "non-polar covalent"
What is the name for a charged group of covalently bonded ions?
polyatomic ion
Ionic compounds do not form molecules, but form a different type of structure instead. What is this structure called (two words)?
crystal lattice
What is the "sea of electrons"
delocalized electrons that move freely throughout the atoms of an entire metal
What is a London dispersion force?
the intermolecular attractions resulting from the constant motion of electrons and the creation of instantaneous dipoles
