Exercise 6: Name that element
Make a list of the 12 elements that do not have symbols based on their English names. Include
the English name, the symbol, the language of the original name and the original name in a
table.
Find six of the elements named after famous scientists. List the scientist, the name of the
element and the symbol.
Four of the elements are named after planets. List the name of the planet, the name of the
element and the symbol.
Four countries and two continents have also been used to name elements. List them including
the name of the country or continent and the symbol. Make sure you know the difference
between countries and continents.
One of the states of the United States of America has an element names after it. Which one?
Can you find out why?
Superman’s birthplace has the same name as an element. Which element is that?

Exercise 7:
Create a 'How to read the periodic table' help sheet:
https://www.youtube.com/watch?v=yADrWdNTWEc
Must include:
How to identify the individual elements
Where to find/calculate the atomic number, atomic mass and number of neutrons
What the placement of the element in the table can tell us about it.
Exercise 8:
Change the order of the items in the last four columns to match the dates of the first column.

model
Atoms
consisting of
a positive
nucleus with
electrons in
certain orbits
of fixed
energy
called
‘shells’.

Matter made
up of tiny
indivisible

observations
of pure
substances.

Exercise 9:
Draw straight lines matching each term on the left with its definition on the right.
atom
Negatively charged particle that orbits around the nucleus of an
atom.
Pure substance made up of atoms of only one type.
proton
Central part of an atom, containing protons and neutrons.
