VI. Listening

  1. Fill in the gaps with the following words: rich, splits, teeth, time, stable(2,) strong, coins, everywhere, shell(2), light up ,cold, right(2), next to

  2. Now listen to a “Periodic Table” song and check if you were right.

There is hydrogen and helium then lithium, beryllium,

Boron, carbon……., nitrogen all through the air

With oxygen so you can breathe and fluorine for your pretty……

Neon to light up the signs, sodium for salty times

Magnesium, aluminum, silicon, phosphorus then sulphur, chlorine and argon,

Potassium and calcium so you’ll grow………

Scandium, titanium, vanadium and chromium and manganese

This is periodic table

Noble gas is…………

Halogens and alkali react aggressively

Each period will see new outer…….

While electrons are added moving to the …..

Iron is the 26th then cobalt, nickel ………you get

Copper, zinc and gallium, germanium and arsenic

Selenium and bromine film while krypton helps……..your room

Rubidium and strontium, then yttrium, zirconium, niobium, molybdenum, technetium

Ruthenium, rhodium, palladium, silver-ware then cadmium and indium

Tin cans, antimony then tellurium and iodine and xenon and then cesium and…

Barium is 56 this is where the table ……..where lanthanides have just begun

Gold to make you …….till you grow old; mercury to tell you when it’s really ……

Thallium and lead then bismuth for your tummy, polonium astatine wouldn’t be yummy

Radon, francium will last a little……, radium then actinides at 89

This is periodic table

Noble gas is …….

Halogens and alkali react aggressively

Each period will see new outer ……

While electrons are added moving to the ……

Actinium, thorium, protactinium, uranium, neptunium, plutonium, americium, curium

Berkelium, californium, einsteinium, hermium, mendelevium, nobelium, lawrencium,

Rutherfordium, dubnium, seaborgium, bohrium, roentgenium, copernicum, ununtrium,

Flerovium,ununpentium, ununoetium and we’re done!!!!
