7) Which is a property shared by most molecular compounds?
A
low melting point
B
nonpolar bonds
C
high boiling point
D
high melting point
8) When an atom loses an electron, it becomes a
A
neutral atom
B
negative ion
C
positive ion
D
neutral ion
9) Magnesium bromide is an ionic compound with the chemical formula MgBr2. (the 2 should be a subscript) What does the '2' tell you?
A
There are two magnesium ions to every bromide ion
B
Bromide has a -2 charge
C
There are two bromide ions for every magnesium ion
D
Bromide has a +2 charge
10) In the chemical formula for an ionic compound, which item is written first?
A
the name of the negative ion
B
the charges
C
The name of the positive ion
D
the subscripts
11) The chemical name for the compound with the formula Na2S is (the 2 is a subscript)
A
sodium sulfide
B
magnesium sulfide
C
sodium flouride
D
lithium oxide
12) What is a double bond
A
two pairs of electrons shared between two atoms
B
one pair of electrons shared between two atoms
C
two pairs of electrons shared between four atoms
D
a bond between two atoms
13) Electrons involved in bonding between atoms are
A
positively charged
B
valence electrons
C
inside the nucleus
D
closest to the nucleus
14) What are two ways that a proton and a neutron are similar?
A
They are located in the nucleus and have a charge of zero
B
They are located in the nucleus and have an atomic mass of 0
C
They are located in the nucleus and have a charge of +1
D
They are located in the nucleus and have an atomic mass of 1
15) How is it possible for an atom to have no charge even though it is made up of protons, neutrons and electrons?
A
None of these answers
B
The number of electrons and neutrons are equal, so the charge is zero
C
The number of protons and neutrons are equal, so the charge is equal
D
The number of protons and electrons are equal, therefore the charge is equal
16) Why is it UNnecessary to include the electrons when determining the mass of an atom?
A
The electrons are not located in the nucleus, so they don't count
B
An electron has a negative charge
C
The mass of the electrons is so large that it can't be added
D
The mass of the electron is so small that it wouldn't change the mass
