state of matter, metal,
non-metal, metalloid,
structure, hardness etc.)
3. Compare the chemical
properties of the elements
(description of how the
elements reacts with
other elements such as:
whether an element is
corrosive, combustible or
flammable) and relate to
this electron structure.

group numbers and family
names.

Beryllium is a hard brittle
metal with a greyish-white
surface; its density is
1.8grams for a centimetre
cubed. It has a melting point
of 1,287 degrees and a boiling
point of 2,500 degrees.
Beryllium reacts with acids
and water to form hydrogen
gas. It reacts briefly with
oxygen in the air to form
Beryllium oxide (Be0). This
provides oxygen not to react
any more with the metal.
Beryllium is a metal because it
is a excellent conductor of
electricity, its shiny and
malleable its group number is
II.
Be-9= Beryllium stable
isotope 2P, 2E, 5N and 2
shells
13Be =Unstable
isotope 2P, 8E, 3N
and 3 shells
Beryllium Chloride
(BeCl 2 )
Beryllium Hydroxide
(Be(OH) 2 )
Beryllium was discovered by a
French chemist named LouisNicholas Varlequin. It was
originally named glucinium
because it was sweet-tasting
but the name was changed to
Beryllium in 1957.
Beryllium’s main use is metal
alloys which conduct
electricity because they are
tougher, stiff and are lighter
than other alloys used in
helicopters, now coppermetal beryllium alloys are
used in computers, home
appliances, circuit boards and
etc, because they are
stronger, less likely to fatigue
and rust.
