3.4 Molecules And Ions Flashcards
covalent bonds are formed when atoms
share e-‘s
the forces that hold chemicals together are called
chemical bonds
molecules can be represented by its
chemical formula
a structural formula shows
individual bonds
the relative sizes and orientation in a molecule is represented by
space-filling model
ball-and-stick models show
the relative spacing in a molecue
when an e- is subtracted from an atom, the charge becomes ____ (+/-) and the radius _______(increases/decreases)
+
decreases
when an e- is given to an atom, the charge of the atom is ____ (+/-) and the radius _____ (increases/decreases)
-
increases
a cation is
a positively charged ion
an anion is
a negatively charged ion
ionic bonding occurs because of
the force of attraction between oppositely charged particles
a solid composed of oppositely charged ions is called a(n)
ionic solid
