Also, do past papers. when would u recommend to do past papers in year 11 around January I'm confused because I still need to cover the content we learned from year 10 and my mocks are in November maybe December and I really want to get grade 7 and 8.

      Hi RedoStone35, making these videos takes a lot of time and effort, I do this so I can help as many students as possible achieve the best grade they can. I'm sorry you don't find my channel helpful. I struggle severely with dyslexia, this means writing such long videos, with long complicated words in, is extremely difficult for me.

      Hi MFZ 285, watch the long whole topic videos making notes as you go along, Pause, rewind and copy down notes and diagrams. I suggest you watch this in combination with using my FREE revision guide which you can get by signing up to my mailing list mailchi.mp/161c4e43b8bf/primrosekitten
      Also available on my website www.primrosekitten.com/collections are workbooks and an online course. I've rewritten the specification and it clearly shows you everything you need to know. Do as many practice questions as you can, I've written loads, use past papers, use other workbooks.

    Compound: 2 or more elements chemically bonded
    Nucleas : protons and neutron
    Both mass of 1 proton and neutron but electrons mass is 1/2000 and electron charge is -1
    Electron found outer shell.
    Atomic number ( protons and electrons)
    Atomic mass is bottom , is the larger one (protons and neutrons)
    Neutrons is mass-atomic
    Atomic number is protons and electrons the smaller one
    Water H20-> H2 plus oxygen
    Need to balance equations
    Carbon dioxide is CO2
    Water H2O
    Oxygen O2
    Nitrogen H2

    Hydrochloridic acid HCI
    Sulfuric acid H2SO4
    Mixtures lots of differents some chemically bonded some not
    Distaillion: sperate by bioling point
    Evaporation p: remove liquid and leave solid that has been dissolved
    Filtration: large particles of solid particles will stay, liquid will drop throigh paper

    this is so wrong. Neils Bohr discovered it in 1914 then James CHADWICK discovered it in 1932. We use CHADWICKS model of an atom NOT Neils Bohrs

      She is not wrong. Chadwick discovered neutrons in 1932 but we don't use his model- we use Bohr's model of the atom - search it up

    ype of atom.
    Compound: 2 or more elements chemically bonded
    Nucleas : protons and neutron
    Both mass of 1 proton and neutron but electrons mass is 1/2000 and electron charge is -1
    Electron found outer shell.
    Atomic number ( protons and electrons)
    Atomic mass is bottom , is the larger one (protons and neutrons)
    Neutrons is mass-atomic
    Atomic number is protons and electrons the smaller one
    Water H20-> H2 plus oxygen
    Need to balance equations
    Carbon dioxide is CO2
    Water H2O
    Oxygen O2
    Nitrogen H2
    Ammonia. NH3
    Hydrochloridic acid HCI
    Sulfuric acid H2SO4
    Mixtures lots of differents some chemically bonded some not
    Distaillion: sperate by bioling point
    Evaporation p: remove liquid and leave solid that has been dissolved
    Filtration: large particles of solid particles will stay, liquid will drop throigh paper
    Fraction dissipation take things off at different biolong point
    Plumb pudding by JJ Thompson + charge in middle delocalised electron
    Ratherford fired alpha particles at sheet of gold, some went throigh, some didn’t. Created nuclear model
    Rutghford made nucleas ,
    Chadwick neutrons
    Bone current model
    Magnesium
    Electrons 12
    Group 2
    Group 1 alkali
    Alaknine models
    Group 7 halogen
    Group 8 Nobel
    Chunk in middle transition models
    Mendeelev arranged by mass and left gaps and similar prototies, can predict properties
    Nobel gases full outer shell.
    Unreaftive
    Helium used in balloons
    Group7
    Non metals,
    Highly reactive at top
    Bioloinh point low at top, high Bp at top
    Alkali metals group 1
    Metal+oxygen-> metal oxide
    Metal+water-> metal hydroxide
    Transitions metals hard, shiny, can be used in jewlry, wires, copper is blue iron is light green iron 3 orange brown
    Cobalt is blue
    Alpha particle helium nuclei they have a 2+ charge
