  • Also known as the Alkali metals

  • All of the metals reactvigoursly or even explosively with cold water. Due to their desire of wanting to get rid of the 1 valance e-

  • When any of the group 1 metals is melted, the metallic bond is weakend enough for the atoms to move freely, and is broken completely when the boiling point is reached

  • Both the melting point and boiling point decreases down the group Ex: Na 371, K 337 degrees

  • Potassium is used in fertilizers as salt and Sodium is used in street lights

Group 1

Group 2

  • Also known as the Alkaline Earth Metals

  •  Overall Group 2 metal becomes more reactive with water as you go down the group

  • Some physical properties is Berrilyum has a melting point around 1250 degree celcius, Magnesium with approximate 620 degree celcius, but Calcium have a melting point of approximately 800.4 degree celcius.

  • Apart from as you down  the group the melting point falls down. However Mg breaks that trends. The reason behing the melting point becoming lower is because the metallic bonds become weaker

  • Be is used for electrical contacts,Mg is used to treat people with server heart attacks
