Atoms and Elements
- Describe the differences
between elements, compounds
and mixtures
- ELements- Substance only
made of one type of atom
- Compounds- Substance
made from more that one
type of atom.
- MIxture- Substance which has
more than one type of element
but not chemically bonded
together
- ELements- Substance only
made of one type of atom
- Describe the structure of an atom in
terms of electrons and a nucleus
containing protons and neutrons
- An atom has a nucleus in middle
containing protons and neutrons
surrounded by shells containing
electrons
- An atom has a nucleus in middle
containing protons and neutrons
surrounded by shells containing
electrons
- Describe the build-up of electrons in
‘shells’ and understand the significance
of the noble gas electronic structures
and of valence electrons.
- Each atom has outer shells containing electrons. The
first outer shell of an atom is capable of containing
only 2 electrons while the other can contain up to 8
electrons. Noble gases structure is the outer shell is
filled and there is no more need for electrons for a
complete outer shell.
- Each atom has outer shells containing electrons. The
first outer shell of an atom is capable of containing
only 2 electrons while the other can contain up to 8
electrons. Noble gases structure is the outer shell is
filled and there is no more need for electrons for a

- State the relative charges and
approximate relative masses
of protons, neutrons and
electrons
- Define atomic (proton)
number and mass
(nucleon) number
- Atomic number- number
of proton.
- Nucleon number- number
of proton and neutron
- Atomic number- number
of proton.
- Define isotopes
- Isotopes are the atoms of the same
element which have the same number
of the proton but a different nucleon
number.
- Isotopes are the atoms of the same
element which have the same number
of the proton but a different nucleon
number.
