1.When is an atom stable?
a.when its electrons are evenly distributed through its energy levels
a.when its lowest occupied energy level is filled with electrons
a.when its highest unoccupied energy level is filled with electrons
when its highest occupied energy level is filled with electrons
2.Which description applies to an element that has two valence electrons?
a.reactive metal
a.nonreactive metal
a.reactive nonmetal
nonreactive nonmetal
3.How do sodium and chlorine both achieve stable electron configurations when they react?
a.An electron is transferred from the sodium atom to the chlorine atom.
a.An electron is transferred from the chlorine atom to the sodium atom.
a.Both atoms gain one electron.
Both atoms lose one electron.
4.Why do ionic compounds tend to have high melting points?
a.Ionic compounds contain more than one element, which causes a high melting point.
a.Ionic compounds cannot absorb energy efficiently because they contain ions.
a.An ionic compound contains metal atoms that raise its melting point.
A strong electrical attraction means ions require a lot of energy to move apart.
The ratio of aluminum ions to chloride ions in aluminum chloride (AlC13) is 3:1.
True
False
When the highest occupied energy level of an atom is filled with electrons, the atom is stable and not likely to react.
true
false
All the noble gases have stable electron configurations with eight valence electrons
True
False
A sodium atom has one more electron than a neon atom. Removing one electron would give sodium a stable configuration
True
False
Within a period, what happens to the atomic radius as the atomic number of the elements increases?
Atomic radius increases
Atomic radius decreases
Atomic radius stay the same
Compare the atomic and ionic radii for potassium (K)
The ionic radius for potassium is much smaller than its atomic radius.
The ionic radius for potassium is much larger than its atomic radius.
The ionic radius for potassium the same as the atomic radius.
Compare the atomic and ionic radii for bromine (Br).
The ionic radius for bromine is much smaller than its atomic radius.
The ionic radius for bromine is much larger than its atomic radius.
The ionic radius for bromine is the same as the atomic radius.
•An ionic bond is the force that holds cations and anions together. An ionic bond forms when electrons are transferred from one atom to another.
True
False
The lower the ionization energy, the harder it is to remove an electron from an atom.
True
False
Solid ionic compounds are good conductor of electric current.
True
False
When the solid ionic compounds melts, the lattice breaks apart, and the ions are free to flow.
so, Molten sodium chloride is an excellent conductor of electric current
True
False
