What is the origin of the symbol for platinum?
Platinum has the symbol Pt, its atomic number is 78, and its atomic weight is 195.09. The name is derived from the Spanish platina, meaning “silver.” Platinum was discovered in South America independently by Antonio de Ulloa in 1735 and by N. Wood in 1741, but it had been in use by pre-Columbian Indians.

Where is boron naturally found?
Boron is a naturally occurring element that is found in oceans, sedimentary rocks, coal, shale, and some soils. Boron is released into the environment from the oceans, volcanic and other geothermal activities such as geothermal steam, and natural weathering of boron-containing rocks.
Why is platinum so unreactive?
Why is it so incredibly unreactive? While it’s true that Pt has two d-bands crossing the Fermi level, the energy gap between the two orbitals is large enough to make the metal very chemically stable.
What is platinum mostly used for?
Platinum is commonly known for being used in the manufacturing of jewellery but its main applications spread to catalytic converters, electrical contacts, pacemakers, drugs and magnets.
What are cool facts about boron?

Chemical Symbol for Boron Boron is a chemical element with atomic number 5 which means there are 5 protons and 5 electrons in the atomic structure. The chemical symbol for Boron is B. Significant concentrations of boron occur on the Earth in compounds known as the borate minerals.
Where can boron be found on the Earth?
Significant concentrations of boron occur on the Earth in compounds known as the borate minerals. There are over 100 different borate minerals, but the most common are: borax, kernite, ulexite etc. Natural boron consists primarily of two stable isotopes, 11B (80.1%) and 10B (19.9%).
Where does the name Platinum come from on the periodic table?
Platinum is a chemical element with the symbol Pt and atomic number 78. It is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal. Its name is derived from the Spanish term platino, meaning “little silver”. Platinum is a member of the platinum group of elements and group 10 of the periodic table of elements.
