  1. 1What are atoms?Imagen de la pregunta 1
    1. AAtoms are heavy solid balls.
    2. BAtoms are tiny visible particles.
    3. CAtoms are the building blocks of every substance in the world.
    4. DAtoms are Lego blocks.
  2. 2Which of the following are metallic?Imagen de la pregunta 2
    1. AIron
    2. BSilicon
    3. CCobalt
    4. DCalcium
    5. EPhosophorus
    6. FSulfur
    7. GSilver
    8. HUranium
    9. IKrypton
  3. 3Which of these properties best describes the non-metallic elements?Imagen de la pregunta 3
    1. ADull
    2. BMalleable
    3. CBrittle
    4. DConduct heat
    5. EDuctile
    6. FDoesn't conduct electricity
  4. 4Elements are made up of just one type of atom.However, the atoms in elements can be arranged in different ways, these ways are :
    -[blank_start]Monatomic[blank_end]
    -[blank_start]Molecules[blank_end]
    -[blank_start]Lattices[blank_end]    Imagen de la pregunta 4
    1. AMonatomic
    2. BMolecules
    3. CLattices
  5. 5What are the 6 monatomic elements?Imagen de la pregunta 5
    1. AHelium,Nitrogen,Carbon,Oxygen,Hydrogen,Phosphorus
    2. BXenon,Radon,Neon,Argon,Helium,Krypton
    3. CSulfur,Oxygen,helium,hydrogen,neon,Argon
    4. DXenon,Radon,Neon,Argon,Helium,hydrogen
  6. 6In metal lattices,the atoms are only [blank_start]weakly joined[blank_end] to each other.As a result, metals can be bent and drawn into [blank_start]wires[blank_end].
    -
    In [blank_start]non-metallic[blank_end] lattices, the atoms are [blank_start]strongly bonded[blank_end] to each other. This makes them hard and [blank_start]brittle[blank_end].    Imagen de la pregunta 6
    1. Aweakly joined
    2. Bwires
    3. Cnon-metallic
    4. Dstrongly bonded
    5. Ebrittle
  7. 7Wha are the 6 elements that make up your body?Imagen de la pregunta 7
    1. ACarbon
    2. BHelium
    3. CIodine
    4. DHydrogen
    5. ENitrogen
    6. FPhosphorus
    7. GCalcium
    8. HOxygen
  8. 8What is the chemical formula for glucose molecule?
    <--------------------------

    <--------------------------    Imagen de la pregunta 8
    1. AH12,O6,C6
    2. BO6,C6,H12
    3. CC6,H12,O6
    4. DC6,O6,H12
  9. 9[blank_start]Alloys[blank_end] are a [blank_start]mixture[blank_end] of a metal with other metals or non-metals.Alloys are particularly important because they often have very [blank_start]different[blank_end] and [blank_start]useful[blank_end] properties compared to [blank_start]pure metal[blank_end]. For example:-
    -[blank_start]Stainless steel[blank_end] for tools and cutlery
    -[blank_start]Brass[blank_end] for doorknobs
    -[blank_start]Sterling silver[blank_end] for jewellery.    Imagen de la pregunta 9
    1. AAlloys
    2. Bmixture
    3. Cdifferent
    4. Duseful
    5. Epure metal
    6. FStainless steel
    7. GBrass
    8. HSterling silver
  10. 10Scientists proposed that matter was composed of atoms well after STMs were invented.Imagen de la pregunta 10
    1. AVerdadero
    2. BFalso
