Reactivity series

• Metal A will displace metal B if it has a higher position on the reactivity series.
• Reactivity increases down group 1, as atomic radius increases and metallic bonding decreases.
• Reactivity increases from top to bottom of the reactivity series.
• Alkali metals (group 1) have low melting points because they have weak intermolecular forces between atoms.
• Elements that are more reactive can be found at the top of the reactivity series.
• The reactivity series is based on the tendency of elements to lose electrons and form positive ions.
• Less reactive metals are harder than more reactive ones due to their stronger metallic bonds.
• The reactivity series is based on the tendency of elements to lose electrons or gain them.
• How is the reactivity in Group 1 metals ?

  The reactivity of Group 1 elements, increases as you go down the group.
