IONIC and COVALENT BONDING (B)
Review: Fill in the blanks.
When a metal and a nonmetal bond, they form a _______________ bond. This type of bond involves
_______________ and _______________ valence electrons, where the metal _______________ its
electrons and the nonmetal _______________ electrons. This type of bond forms due to the attraction
between _______________ and _______________ charged ions. When two or more nonmetals bond,
they form a _____________ bond. This type of bond involves _____________ pairs of valence electrons.
This type of bond forms due to the attraction each atom has to the electrons in between them.

IONIC and COVALENT BONDING (B)
Review: Fill in the blanks.
When a metal and a nonmetal bond, they form an ionic bond. This type of bond involves losing and gaining valence electrons, where the metal loses its electrons and the nonmetal gains electrons. This
type of bond forms due to the attraction between positively and negatively charged ions. When two or
more nonmetals bond, they form a covalent bond. This type of bond involves sharing pairs of valence
electrons. This type of bond forms due to the attraction each atom has to the electrons in between
them.
