Stats

• What happens to the metal in the reaction?

  The metal floats on the surface
• How does reactivity change in group 1 elements?

  Reactivity increases as you go down group 1
• Why does reactivity increase down group 1?

  Weaker electron attraction due to distance
• What happens to the outer electron as you go down group 1?

  The outer electron is further away
• What does it mean when an electron is lost more easily?

  It indicates higher reactivity of the metal
• What is absorbed in the reaction involving sodium?

  The oxygen gets absorbed/used in the reaction
• What is a characteristic of sodium's melting point?

  Sodium has a high melting point
• Why does sodium have a high melting point?

  Because the intermolecular forces are strong
