Chemistry
- Atomic structure and the periodic table
- Model of the atom
- Plum pudding
- Positive "pudding" with
negative "plums"
- Positive "pudding" with
negative "plums"
- Rutherford
- Mass in the positively
charged nucleus and
negative electrons
orbiting
- Gold foil experiment where gamma
particles were fired through some
gold foil and some bounced back
while most went through so
Rutherford concluded that there
was a nucleus imn the middle that
was positive
- Mass in the positively
charged nucleus and
negative electrons
orbiting
- Bohr
- Discovered that electrons
orbit at fixed distances
(electron shells)
- Discovered that electrons
orbit at fixed distances
(electron shells)
- Chadwick
- Discovered particles in the
nucleus with no charge -
neutrons
- Discovered particles in the
nucleus with no charge -
neutrons
- Plum pudding
- Elements and compounds
- Elements are a
single type of atom
- Compounds are made
of multiple bonded
atoms
- Mixtures are made of
different elements and/or
compounds that aren't
bonded
- Elements are a
single type of atom
- Chemical reactions
and equasions
- Compounds are broken
up or formed
- At least one new
substance is
created
- Measurable
energy change
- No atoms are
created or destroyed
- Compounds are broken
up or formed
- The atomic number is
the number of protons
and also the number of
electrons in an atom
- The mass number is the relative mass of
an atom - made up of the number of
protons + the number of neutrons
- Isotopes
- SAME number of protons but
DIFFERENT number of neutrons
- SAME number of protons but
DIFFERENT number of neutrons
- The periodic table
- Noble gasses
- Group 0
- Unreactive
- Used in light bulbs
- Monomatic - they
exist in single atoms
- Low boiling point
- Low density
- Full outer shell
- Group 0
- Alkali metals
- Group 1
- 1 electron in outer shell
- Very reactive
- Group 1
- Transition metals
- Between groups 2 and 3
- Between groups 2 and 3
- Organisation
- Groups
- Vertical
- The same number of
electrons in the outer shell
- Similar properties -
predictable
- Vertical
- Periods
- Horizontal
- The same
number of shells
- Horizontal
- Groups
- Noble gasses
- Model of the atom
- Bonding, structure and properties fo matter
- Quantitive chemistry
- Chemical changes
