1) Unlike _______ bonds, ______ bonds can form between two atoms of the same element.
A
ionic, covalent
B
covalent, ionic
C
hydrogen, molecular
D
molecular, hydrogen
2) When ionic or covalent bonds are formed, chemical compounds are created. Which of the following does not represent a compound?
A
NO
B
BaBr
C
Na atoms
D
PO
3) In an ionic bond, nonmetals are most likely to
A
gain electrons
B
share electrons
C
lose electrons
D
cancel electrons
4) What would happen if a sodium (Na) atom and a neon (Ne) atom were put near one another?
A
An ionic bond would form
B
A bond would not form
C
They would cancel each other out
D
A covalent bond would form
5) Atoms join with other atoms by bonding with them in order to become as chemically _______ as possible.
A
inert
B
unstable
C
electrified
D
stable
6) When forming a chemical bond only the ________ electrons participate in the bonding process.
A
inner shell
B
ionic or covalent
C
outer shell
D
ionized
7) The noble gases rarely participate in chemical bonding because
A
they are gases and gases are less volatile
B
sharing electrons would not involve enough energy
C
they have an atomic structure similar to hydrogen
D
their valence electron shells are full
8) When atoms bond covalently with other atoms to form new substances the atoms ___________ electrons.
A
lose and gain
B
share and transfer
C
share
D
transfer
9) When a covalent bond forms between two atoms how many atoms have a full outer shell of electrons?
A
it depends on what the atoms are
B
zero
C
two
D
one
10) What makes the outer shell electrons important is that they
A
determine the chemical reactivity of the atom.
B
tell you what element you're dealing with if you only know how many electrons are in the outer shell
C
are not really important so they can be lost easily.
D
will always seek out atoms that have the same number of outer shell electrons
