ELEMENTS ON THE PERIODIC TABLE
Do you think they are named after people or places?
Examples…
HYDROGEN: (the 1st element on the periodic table and is colourless, odourless and a highly flammable gas)
Hydrogen was not named after a person or a place. The origin of the name ‘Hydrogen’ comes from the Greek words ‘hydro’ meaning water and ‘genes’ meaning generator.
LEAD: (the 82nd element on the periodic table and is a soft, silver metal)
Lead was not named after a person or a place. The origin of the name ‘Lead’ comes from the Anglo-Saxon word ‘lead;. The origin of the symbol Pb comes from the Latin word ‘plumbum’ meaning ‘liquid silver’.
ZINC: (30th element on the periodic table and is a silver/white metal which is used to prevent corrosion and rust on iron and steel products)
Zinc was not named after a person or a place. The origin of the name ‘Zinc’ comes from the German word ‘zinc’.
GENERAL STATEMENT:
Out of all the elements on the periodic table, only about 13 elements are named after people, and 12 are officially accepted.
How do these elements behave?
Examples…
HYDROGEN:
Hydrogen is an explosive gas.
LEAD:
Lead is a fairly unreactive, dense and soft metal.
ZINC:
Zinc is a reactive but relatively soft metal.
GENERAL STATEMENT:
There is a similarity between the elements that have been named after someone. All those elements are either in the Lanthanides, Actinides or Transactinide which are all high on the periodic table Transactinide have an atomic count that is almost the highest known today.
What is the appearance of elements?
HYDROGEN:
Hydrogen is a colourless gas.
LEAD:
Lead is generally a blue/grey colour and produces a soft glow when cut. However, it discolours in moist air to form a dull grey coating.
ZINC:
Zinc comes across as a brittle, blue/grey metal that tarnishes in moist air to form a layer of carbonate. It burns with a bright blue/green flame.
GENERAL STATEMENT:
All Lanthanide elements have an appearance of a silver solid
Actinides all have an appearance of a silver solid but are all stored in protective containers and handled with protective gear. Transactinide are just more dangerous and are handled with even more precautions.
