Question 7

formed by the transfer of electrons
from an atom of low ionization
energy (alkali and alkaline earth
metal) to a more electronegative
element (halogen and oxygen)

Answer 7

IONIC BOND

Question 8

bond in which two electrons are
shared between atoms

Answer 8

Covalent Bond

Question 9

–formed when
electrons are shared equally
between two atoms with the same
or almost the same
electronegativity

Answer 9

Covalent compounds

Question 10

Non-bonding pairs are called ____

Answer 10

LONE PAIRS

Question 11

pairs of valence electrons that
are not involve in covalent bond formation

Answer 11

LONE PAIRS

Question 12

This is formed from sharing of electrons
between two atoms with different
electronegativity.

Answer 12

Polar Covalent Bond

Question 13

the ability of an atom to attract toward itself
the electrons in a chemical bond.

Answer 13

ELECTRONEGATIVITY

Question 14

property that helps us distinguish a nonpolar
covalent bond from a polar covalent bond

Answer 14

ELECTRONEGATIVITY

Question 15

A bond formed wherein one
furnishes both the bonding pair of
electrons.

Answer 15

Coordinate Covalent Bond

Question 16

consists of group of cations held in
a fixed position in the metal and
the valence electrons which are
free to move about among the
different electron clouds.

Answer 16

Metallic Bond

Question 17

attractive
forces between molecules

Answer 17

Intermolecular forces

Question 18

Very weak forces of
attraction between non-polar molecules

Answer 18

Van der Waals

Question 19

is an attractive force
that exists between the hydrogen of one
molecule and the more electronegative
portion of another molecule

Answer 19

Hydrogen Bond

Question 20

is an attractive force
between polar molecules

Answer 20

Dipole Bond

Question 21

The use of two or more Lewis Structures to represent a particular molecule.

Answer 21

Resonance

Question 22

– is one of the two or
more Lewis Structures for a single molecule
that cannot be represented accurately by only one Lewis Structure.

Answer 22

Resonance Structure

Question 23

Two polar molecules align so that
OPPOSITE CHARGES are matched
(electrostatic attraction)

Answer 23

DIPOLE-DIPOLE

Question 24

A dipole can induce (cause) a temporary dipole to form in a non-
polar molecule

The molecules then line up to
match opposite charges

Answer 24

Dipole-Induced Dipole

Question 25

A temporary dipole forms in a non- polar molecule which leads to a temporary dipole to form in ANOTHER non-polar molecule

Answer 25

Dispersion Forces

Question 26

is the ONLY intermolecular attraction that occurs between non-polar molecules

Answer 26

Dispersion

Question 27

simply shows the exact number of each type of atom present. It tells you nothing about the bonding within the compound

Answer 27

MOLECULAR FORMULA

Question 28

gives the simplest possible whole number ratio of the different types of atom within the compound

Answer 28

EMPIRICAL FORMULA

Question 29

formula that shows the simplest whole number ration

Answer 29

EMPIRICAL FORMULA

Question 30

is also text-based here each carbon atom is listed separately with atoms attached to it following an exception is cyclic parts of molecules example benzene where the carbons are grouped

Answer 30

CONDENSED FORMULA

Question 31

a displayed formula shows all of the atoms and all of the bonds present in an organic compound the bonds are represented as lines

Answer 31

DISPLAYED FORMULA

Question 32

Similar to displayed formula not all bonds are shown although all atoms are still indicated using subscript numbers. Carbon- hydrogen bonds are often simplified

Answer 32

STRUCTURAL FORMULA

Question 33

formula which shows how the molecules are bonded to one another in a molecule

Answer 33

STRUCTURAL FORMULA

Question 34

most hydrogen atoms are omitted and lines and or vertices represent carbons. Functional groups and atoms other than carbon or hydrogen are still shown. Easiest to draw and commonly used

Answer 34

SKELETEAL FORMULA
