how many are the natural occuring elements
94
how many are the synthetic elements
24
synthetic elements are
- do not occur naturally
- created artificially
- Radioactive and decay rapidly into lighter elements
- as the product of atomic bombs or experiments
- Used in nuclear reactor and particle accelerator
are the heart of a
nuclear power plant. They contain
and control nuclear chain reactions
that produce heat through a
physical process called fission. That
heat is used to make steam that
spins a turbine to create electricity.
Nuclear reactors
contain
and control nuclear chain reactions
that produce heat through a
physical process
fission
is a special
machine that speeds up charged
particles and channels them into a
beam. When used in research, the
beam hits the target and scientists
gather information about atoms,
molecules, and the laws of physics.
particle accelerator
is a silvery, shiny radioactive
metal. _ is commonly used in
smoke alarms, but has few other uses. It has
the potential to be used in spacecraft
batteries in the future. Currently plutonium is
used but availability is poor so alternatives are
being considered.
Americium
americuim is named after _ and produce by the group of
americans
1944
Glenn T. Seaborg
atomic symbol and no. of americium
Am 95
Named after Marie and Pierre Curie - couple who
both were known for their research on their
radioactivity.
curium
Main uses: as a fuel for Radioisotope Thermal
Generators (RTGs) on board satellites, deep space
probes, planetary surface rovers and in heart
pacemakers, and as a alpha emitter for alpha particle
X-Ray spectrometry, again particularly in space
applications. Toxic to the human body due to being a
heavy metal and its high level of radioactivity. The
most common risk is bone tumors.
curium
atomic symbol and no. of curium
Cm 96
Presently, the element is not used biologically or for
technological purposes.
It was used for the atmospheric nuclear weapons
tests between 1945 and 1980. The only use of _ has been in the synthesis
of heavier elements such as tennessine.
Even low-dose exposures are carcinogenic after
extended exposure. The current generation, the one in
utero, and all that follow may suffer cancers, immune
system damage, leukemias, miscarriages,
stillbirths, deformities, and fertility problems.
berkelium
atomic symbol and no. of berkelium
Bk 97
It is used in portable metal
detectors, for identifying gold and
silver ores, to identify water and oil
layers in oil wells and to detect
metal fatigue and stress in
aeroplanes. _ has no known biological
role. Toxic due to its radioactivity.
californium
atomic symbol and no. of californium
Cf 98
accelerated aging.
Only tiny amounts of einsteinium have
ever been produced; it is mainly used
in scientific studies.
It has a few medical uses but they are
not commercial. It is used majorly to
study radiation damage, targeted
radiation medical treatments and
accelerated aging.
einsteinium
atomic symbol and no. of einsteinium
Es 99
Named after American nuclear
chemist Glenn T. Seaborg
Since only a few atoms of
_ have ever been made,
there are currently no uses for
_ outside of basic
scientific research.
seaborgium
atomic symbol and no. of seaborgium
Sg 106
a synthetic
element that can only be made a
few atoms at a time, does not
have a commercial use.
At present, it is only used in
research.
Rutherfordium
atomic symbol and no. of rutherfordium
Rf 104
is only used for
research purposes in scientific
studies, to better understand its
properties, and to create heavier
elements.
Roentgenium
atomic symbol and no. of reontgenium
Rg 111
Named after Danish Physicist
Niels Bohr.
There are no known uses outside
of research for _ . Because
of this, it is only used to study its
physical properties and
synthesize isotopes of other
elements.
bohrium
atomic symbol and no. of bohrium
Bh 107
An extremely radioactive
synthetic element.
Since only a few atoms of
tennessine have ever been
produced, it currently has no uses
outside of basic scientific
research.
darmstadtium
atomic symbol and no. of darmstadtium
Ds 110
