• Discovered in 1746
by a Chemist named
Andreas Marggraf in
• The name originates
from “Zin”, which is a
State at room temp.: Solid
Melting point: 419.58 ° C
Boiling point: 907 ° C
Density: 7.133 g/Cm3
Zinc is the most electro-
positive of the common
metals, which makes it
useful as protection
against corrosion in
steam boilers and on
hulls of steel ships.
UsesUsed to form many alloys
Used in electric fuses
Used in metal coating
Used in gutters
Used as rust protection
Can be used as a medical use to treat
Used in roofing and some battery
• Zinc Chloride: Used as deodorant and as a
• Zinc Oxide: Used in paints
• Zinc Sulfide: Used as luminescents, and to
make x-ray and tv screens
• Zinc has 5 isotopes with natural abundance:
Zinc-64, Zinc-66, Zinc-67, Zinc-68, and Zinc-70
• Also has 25 radioactive isotopes
• Zinc-65 is a radioactive isotope that has been
used as a tracer to study physical and
biological events. It is injected into a system
then it gives off radiation, which can be
• Obtained from zinc blende and calamine
• Costs $0.70 /Ib
• One of the most common elements in earth’s
• Found in air, soil, water, and present in
almost all foods
• Foods such as red meats, poultry, and many
cereals are good sources of zinc
• Zinc is an important mineral in the body that helps in the formation of
protein, wound healing, blood formation, supports immune system, it’s
involved in metabolic processes and many more. Adults need 90 milligrams
