Metals
What is a
metal?
METALS ARE
ELEMENTS THAT
ARE SHINY,
MALLEABLE,
DUCTILE , AND
GOOD
CONDUCTORS
OF HEAT AND
ELECTRICITY.
What does it
mean for a
metal to be
malleable &
ductile?
MALLEABLE MEANS
THAT A METAL CAN
BE HAMMERED OR
ROLLED INTO SHEETS
DUCTILE MEAN THEY
CAN BE DRAWN
INTO WIRES
In which groups are metals located on
the periodic table?
Groups 1-13
and some of
groups 14-16
Non metals tend to gain electrons, because they
want to be like the noble gases, so it is easier to
get a full valence level by accepting rather than
kicking an electron out.
Metals tend to lose an electron, because it is
easier for them to get a full valence level by
kicking out an electron.
What occurs when metals bond with
non-metals, specifically looking at
gaining and losing electrons?
Define Ion
AN ION IS AN ATOM OR
MOLECULE WITH A NET
ELECTRIC CHARGE DUE TO
THE LOSS OR GAIN OF ONE
OR MORE ELECTRONS.
When a metal
bonds with a
non-metal which
on become a
positive ion and
which one
become a
negative ion?
THE METAL BECOME A
POSITIVE ION BECAUSE IT
TENDS TO KICK OUT AN
ELECTRON LEAVING
MORE PROTONS MAKING
IT MORE POSITIVE
THE NON-METAL BECOME
A NEGATIVE ION BECAUSE
IT TENDS TO ACCEPT
ELECTRONS.
What is
Metallic
Bonding?
POSITIVELY
CHARGED
METALLIC IONS
ARE
SURROUNDED
BY A SEA OF
ELECTRONS.
What role does
metallic
bonding play in
determining
how malleable
& ductile a
metal will be?
BECAUSE THE OUTERLEVEL ELECTRONS
ARE NOT HELP
TIGHTLY TO THE
NUCLEUS OF AN
ATOM BUT MOVE
FREELY THIS ALLOWS
ATOMS TO BE MORE
FLEXIBLE. ALLOWING
METALS TO BE
SHAPED
AlkiMetals are
different?
THE ARE SOFT
THEY ALSO HAVE
1 VALENCE
ELECTRON
WHICH MAKES IT
SUPER REACTIVE
Alkaline
Earth
Metals?
UNIQUE BECAUSE
THEY ONLY HAVE
TWO VALENCE
ELECTRONS AND
THEY ARE NOT
FOUND FREELY IN
NATURE.
Transition
Metals?
THEY ARE NOT VERY
REACTIVE AND HELP
CREATE MANY
ALLOYS WE CANNOT
LIVE WITH OUT.
TRANSITION METALS
ARE LOCATED IN
GROUPS 3-13
Ionic Bond
VS.
Covalent
Bond
IONIC BONDING: IS THE
COMPLETE TRANSFER OF
VALENCE ELECTRON(S)
BETWEEN ATOMS
COVALENT BONDING: IS A
CHEMICAL BOND THAT
INVOLVES THE SHARING OF
ELECTRON PAIRS BETWEEN
ATOMS
