YR. 8 ATOMIC THEORY: UNIT 2 TERM 1
UNIT:
Atomic Theory
UNIT OVERVIEW: All matter is comprised of atoms that occur on the
periodic table of elements. The structure of these different atoms and the
way in which they combine, is what gives matter varying properties. If a
substance is made up of only one type of atom, it is referred to as an
element. If a substance is comprised of more than one type of element, in
a set pattern, it is referred to as a compound. Elements and compounds
are referred to as Pure Substances.

(I Know I’ve got it when I can …)
1
Understand that all matter is comprised of Accurately and reliably locate elements in
atoms that occur on the periodic table of
the periodic table
elements.
2
Understand the structure of these
Use models to describe, and recognise, the

combine, is what gives matter varying
compounds
properties.
3
Classify a ‘pure substance’ made up of
only one type of atom, as an element.
Define an element accurately
4
Classify a ‘pure substance’, comprised of
more than one type of element (in a set
pattern), as a compound.
Define a compound accurately & use
models to describe, and recognise, the
arrangement of particles in elements and
compounds
5
Understand the use of chemical symbols
to describe the structure of an element or
compound.
Use chemical symbols to describe
elements and to write simple formulas
(including ionic compounds), e.g. water is
H2O & table salt is NaCl.
6
Apply knowledge of safe lab practices to
investigate the chemical reactions
occurring when new compounds are
created.
Apply safe lab practices to investigate the
processes that are occurring during
chemical reactions and explain these
processes using words and chemical
symbols.
Use models to describe, and recognise, the
arrangement of particles in elements and
compounds
