Metals and Non metals

• What is the significance of metals in modern life?


  Metals are essential and commonly encountered in daily life.
• What defines metals in terms of ion formation?


  Metals can form positive ions when they react.
• Where are metals located on the periodic table?


  Metals are located towards the bottom and to the left of the periodic table.
• What percentage of elements in the periodic table are metals?


  Most elements in the periodic table are metals.
• Where are non-metals found on the periodic table?


  Non-metals are at the far right and top of the periodic table.
• How do non-metals behave in terms of ion formation?


  Non-metals don't generally form positive ions when they react.
• What drives atoms to react?


  Atoms react to form a full outer shell by losing, gaining, or sharing electrons.
• Why do metals towards the bottom of the periodic table react more easily?


  They have outer electrons that are far from the nucleus, feeling a weaker attraction.
• What is the energy requirement for metals to form positive ions?


  Not much energy is needed to remove the electrons from metals.
• Why is it difficult for non-metals to form positive ions?


  Non-metals have many electrons to remove or strong attraction to the nucleus.
• What is the preferred method for non-metals to achieve a full outer shell?


  Non-metals prefer to share or gain electrons.
• What are the basic physical properties of metals?


  • Strong and hard to break
  • Malleable (can be bent or hammered)
  • Good conductors of heat and electricity
  • High boiling and melting points
• How do non-metals differ from metals in terms of physical properties?


  • Dull appearance
  • More brittle
  • Not always solid at room temperature
  • Poor conductors of electricity
  • Often lower density
• What are metals defined as in terms of ion formation?


  Elements that can form positive ions when they react
• How are non-metals defined in terms of ion formation?


  Elements that generally don't form positive ions
• What are the general properties of metals?


  • Strong but malleable
  • High melting point
  • Shiny appearance
  • Good electrical and thermal conductors
  • Become more reactive when they lose electrons more easily
  • More reactive towards the bottom left of the periodic table
• What are the general properties of non-metals?


  • Dull appearance
  • Brittle
  • Gain full outer shell by gaining/sharing electrons
  • Low melting point
  • Poor conductors
  • More reactive when they gain electrons more easily
  • More reactive towards the top right of the periodic table
• How do metals achieve a full outer shell?


  By losing electrons
• How do non-metals achieve a full outer shell?


  By gaining or sharing electrons
• How does the reactivity of metals change in relation to their position on the periodic table?


  Metals become more reactive towards the bottom left of the periodic table
• How does the reactivity of non-metals change in relation to their position on the periodic table?


  Non-metals become more reactive towards the top right of the periodic table
• What is a characteristic of metals in terms of conductivity?


  They are good electrical and thermal conductors
• What is a characteristic of non-metals in terms of conductivity?


  They are poor conductors
