|
H - Hydrogen
|
A colourless, odourless and highly flammable gas. |
|
|
He - Helium
|
An inert gas which is the lightest member of the noble gas series. |
|
|
Li - Lithium
|
A soft silvery - white metal belonging to the alkali metal group of chemical elements. |
|
|
Be - Berylium
|
Created through stellar nucleosynthesis, it is short - lived and it is a relatively rare element in the universe. |
|
|
B - Boron
|
Produced entirely by cosmic ray spallation and not by stellar nucleosynthesis it is a low-abundance element in both the Solar system and the Earth's crust. |
|
|
C - Carbon
|
It is nonmetallic and tetravalent making four electrons available to form covalent chemical bonds. |
|
|
N - Nitrogen
|
It is the lightest pnictogen and at room temperature, it is a transparent, odorless diatomic gas. |
|
|
O - Oxygen
|
A colourless, odourless reactive gas and the life-supporting component of the air. |
|
|
F - Fluorine
|
It is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. |
|
|
N - Neon
|
Neon is a colorless, odorless and inert monatomic gas with about two-thirds the density of air. |
|
|
Au - Gold |
In its purest form, it is a bright, slightly reddish yellow, dense, soft, malleable and ductile metal. |
|
|
Ag - Silver |
A soft, white, lustrous transition metal, it possesses the highest electrical conductivity, thermal conductivity and reflectivity of any metal. |
|
|
Ti - Titanium |
It is a lustrous transition metal with a silver color, low density and high strength. It is highly resistant to corrosion in sea water and chlorine. |
|
|
Co - Cobalt |
It is found only in the Earth's crust and is in a chemically combined form, save for small deposits found in alloys of natural meteoric iron. |
|
|
Ar - Argon |
It is the third most common gas in the Earth's atmosphere. |
|
|
Na - Sodium |
It is a soft, silver-white, highly reactive metal and is a member of the alkali metals. |
|
|
S - Sulfur |
It is an abundant, multivalent non-metal. Under normal conditions, sulfur atoms form cyclic octatomic molecules. |
|
|
Mg - Magnesium |
It is a shiny gray solid which bears a close physical resemblance to the other five elements. |
|
|
Al - Aluminium |
It is a silvery - white, soft and nonmagnetic, ductile metal. Aluminium is the third most abundant element, and the most abundant metal in the Earth's crust. |
|
|
P - Boron |
It is produced entirely by cosmic ray spallation and not by stellar nucleosynthesis it is a low-abundance element in both the Solar system and the Earth's crust. |
