CHEMISTRY 1010 EXAM 2 CLEMSON
QUESTIONS WITH CORRECT ANSWERS 2026
Molecule - CORRECT ANSWER -
a unit of matter that results when two or more atoms are joined by covalent bonds
Ionic bond - CORRECT ANSWER -
a bond resulting from the electrostatic attraction of a cation for an anion
Non polar covalent bond - CORRECT ANSWER -
a bond characterized by an even distribution of charge; electrons in the bonds are shared e
qually by the two atoms
Polyatomic ions - CORRECT ANSWER -
charged group of more than one kind of atom joined together by covalent bonds
Electrostatic potential - CORRECT ANSWER -
the energy a charged particle has due to its position relative to another charged particle
Directly proportional - CORRECT ANSWER -
electrostatic potential is to the product of the charges of the particle
s
Inversely proportional - CORRECT ANSWER -
electrostatic potential is to the distance between the particles
Lattice energy - CORRECT ANSWER -
the energy released when one mole of an ionic compound forms from its free ions in the
gas phase
, Bond energy - CORRECT ANSWER -
the energy needed to break one mole of a particular covalent bond in a molecule or polya
tomic ion in the gas phase
Octet rule - CORRECT ANSWER -
atoms of main group elements make bonds by gaining, losing, or sharing electrons to achie
ve a valence shell containing 8 electrons, of 4 electron pairs
Bond length - CORRECT ANSWER -
distance between the nuclear centers of two atoms joined together in a bond
Bonding pair - CORRECT ANSWER -a pair of electrons shared between two atoms
Lone pair - CORRECT ANSWER -a pair of electrons that is not shared between two atoms
Electronegativity - CORRECT ANSWER -
a relative measure of the ability of an atom in a bond to attract electrons to itself when b
onded to another atom
Resonance structure - CORRECT ANSWER -
characteristic of electron distributions when two or more equivalent Lewis structures can b
e drawn for one or more compound
Resonance stabilization - CORRECT ANSWER -
the stability of a molecular structure due to delocalization of its electrons
Formal charge - CORRECT ANSWER -
value calculated for an atomic a molecule or polyatomic ion by determining the difference
between the number of valence electrons in the free atom and the sum of the lone pair el
ectrons plus half of the electrons in the atom's bonding pairs
