metallic bonds - ANSWER formed between two metals, creates a sea of free
moving electrons
metals - ANSWER malleable and ductile
freedom of electrons allows for - ANSWER high conductivity
ionic bonds - ANSWER formed between an anion and cation (metal and nonmetal).
electrons are transferred
electrostatic potential - ANSWER strength of the ionic attraction (form of potential
energy). also called Coulombic Attraction. Eel=2.31 x10^-19 J x nm (Q1xQ2)/D)
when electrostatic potential energy = zero - ANSWER ions are far apart and no
attraction
as ions get closer - ANSWER electrostatic PE decreases and electrostatic
attractions increase
Lattice Energy - ANSWER energy released when ions combine to form a crystalline
solid consists of an ordered three dimensional array of particles called a crystal
lattice
the largest charge and shortest distances (atomic radii) give - ANSWER most
negative Eel and stronger bond.
ATOMIC RADII PATTERNS - ANSWER decreases across a period and increases
down a group (left bottom is greatest)
ionic bonds - ANSWER stronger then others, hard and brittle. create a rigid crystal
covalent bonds - ANSWER form between atoms that share electrons (two
nonmetals)
diatomic molecules - ANSWER bonded to themselves (natures twins), pure
covalent bonds because they share electrons equally
MEMORIZE DIATOMIC MOLECULES - ANSWER H2, N2, F2, O2, I2, Cl2, Br2
polyatomic ions - ANSWER covalently bound molecules that form an ion. combine
with ions of opposite charges to form ionic bonds
