How could a Cu2+ ion form?
A Cu2+ ion could form if a Cu atom gains two protons.
A Cu2+ ion could form if a Cu atom loses two electrons.
A Cu2+ ion could form if a Cu atom loses two protons.
A Cu2+ ion could form if a Cu atom gains two electrons. -
ANSWER-b)
The valence electrons of an atom are those that are
_______________the nucleus. When an atom loses an electron
to become an ion, the electron is lost from the electrons that are
___________________the nucleus. If an atom gains an electron
to become an ion, the electron is added to the electrons that are
____________________from the nucleus. - ANSWER-farthest

When an atom loses electrons, a ______________charged ion
forms. - ANSWER-positively
When an atom gains electrons, a ________________charged ion
forms. - ANSWER-negatively
Protons have a ____________electric charge and electrons have
a __________________electric charge. An atom has a
_______________number of protons and electrons and therefore
has a _______________electric charge. An ion that has gained
an electron has a _______________electric charge. Ions have an
____________number of protons and electrons.

A strong, attractive force occurs between the two ions because
one is positively charged and the other is negatively charged, and
the unlike charges are attracted to one another. This force is a
type of chemical bond called an________________ - ANSWER-
ionic bond.
Compounds held together by ionic bonds are called
__________________ - ANSWER-ionic compounds.
Which of the following statements about ionic compounds are
correct? (Select all that apply.)
a) An ionic compound typically forms between a metal and a
nonmetal.
b) When an ionic compound forms, electrons are transferred.
c) The ratio of elements in any given ionic compound is always
the same.

d) An ionic compound contains positively charged ions but not
negatively charged ions. - ANSWER-a, b and c
Nonmetals tend to gain electrons; when they pick up electrons
from another atom (usually a metal), ions are created.
True
False - ANSWER-True
When two nonmetals react, neither one fully transfers electrons to
the other. Instead, they share electrons. It is this sharing of
electrons that provides the attractive force that holds the atoms
together. This type of chemical bond is called
a__________________ - ANSWER-covalent bond
Which of the following statements about molecules are correct?
(Select all that apply.)
a) Not all molecules are compounds.
b) A molecule contains ions.
c) A molecule forms when electrons are shared in a covalent
bond.
