Reactivity and Valence Electrons
REINFORCEMENT
Review information on reactivity, valence electrons and Lewis Dot structures. Identify each of the following
statements as true or false. If it is FALSE, then change the statement to make it TRUE.
TRUE
FALSE
The octet rule allows chemists to predict the placement of electrons
around the nucleus.
TRUE
FALSE
The octet rule is used to describe the attraction of elements toward
having, whenever possible, eight valence shell electrons (four electron
pairs) in their outer shell.
TRUE
FALSE
Except for Carbon all elements can have eight electrons in their outer
shell.
TRUE
FALSE
Halogens have eight electrons in their valence shells.
TRUE
FALSE
The octet rule generally works for alkali metals, alkaline earth metals and
nonmetals, but not for the transition elements.
TRUE
FALSE
All nonmetals and metals can form compounds that satisfy the octet rule.
TRUE
FALSE
Elements that follow the octet rule have 3 pairs of electrons.
TRUE
FALSE
The most reactive nonmetal is Fluorine (F).
TRUE
FALSE
The most reactive metal is Lithium (Li).
TRUE
FALSE
The octet is a useful rule because it works for all elements.
TRUE
FALSE
Eight is the maximum number of electrons any atom can have.
TRUE
FALSE
Lithium wants to lose one electron.
TRUE
FALSE
Fluorine is not reactive because it has 7 valence electrons (which is close
enough to 8).
TRUE
FALSE
Lewis Dot structures show the valence electrons around an element.
