Unformatted text preview: that have lost or gained electrons are
called (2) . (3) bonding occurs when oppositely charged
ions are attracted to each other. ( 4) bonds result when two
atoms share one or more pairs of electrons. If two pairs of
electrons are shared, a (5) covalent bond is formed.
Unequal sharing of electrons produces a (6) covalent bond,
such as in water molecules. (7) bonds result when molecules
with polar covalent bonds are weakly attracted to ions or
other polar covalent molecules. 4.
7. Molecules and Compounds ❛❛Atoms can combine to form more complex structures.❜❜
Using the terms provided, complete these statements:
Dissociate Molecule 1.
2. A (1) is formed when two or more atoms chemically combine
to form a structure that behaves as an independent unit. A
(2) is a substance composed of two or more different types of
atoms that are chemically combined. H2 and O2 are
examples of a (3) that is not a (4) . On the other hand, an
ionic compound is not a (5) because the ions are held
together by the force of attraction between opposite charges....
