Matter

• How many types of atom are found in an element?

  one type of atom
• What is a compound?

  a substance made from more than one type of atom chemically bonded in a fixed ratio.
• Are groups the columns or the rows in the periodic table?

  The columns
• Are periods the columns or the rows in the periodic table?

  The rows
• How did Mendeleev order the elements?

  In groups with similar chemical properties
• What is the definition of polymers?

  Very long chain molecules of repeating units. There are natural and synthetic polymers.
• What is group 1 of the periodic table?

  Alkali metals
• What is group 7 of the periodic table?

  Halogens
• What is group 8 of the periodic table?

  Noble gases
• What happens when sodium reacts with water?

  It floats and fizzes.
• What happens when potassium reacts with water?

  It floats, fizzes and shows a lilac flame.
• What happens to the melting point of Group 1 metals down the group?

  melting points decrease
• How are transition metals different to Group 1 metals?

  They are harder, stronger and less reactive.
• What is trend for reactivity as you go down Group 7?

  Reactivity decreases down the group. Fluorine is the most reactive.
• What is the trend of melting and boiling points as you go down Group 7?

  melting and boiling points increase as you go down
• What state is Fluorine (F2)?

  Gas
• What state is Chlorine (Cl2)?

  Gas
• What state is Bromine (Br2)?

  Liquid
• What state is Iodine (I2)?

  Solid
• How would you describe the Group 8 elements ( noble gases ) ?

  Unreactive (inert)
• What is the test for hydrogen gas?

  squeaky pop test
• True or False: The total mass of the reactants and products is the same

  True
• True or False: The properties of the reactants and products are the same

  False
• What are the properties of metals?

  They are shiny, good conductors, high melting point, malleable, ductile and strong.
• What are the properties of non-metals?

  They are poor conductors, dull, low MP and BP and brittle
• Metal stays the same and the non-metal changes to the ending of -ide, the metal goes first
• Metal stays the same and the non-metal and the oxygen results with just non-metal ending of -ate
• Non-metal plus oxygen ends with either monoxide, dioxide or brioxide
• Label the diagram

  A) Alkali Metals (Group 1)

  B) Transition Metals

  C) Halogens (Group 7)

  D) Noble gases (Group 8)
