C2-11 Group 0

The group 0 elements are also know as....

• Group 8

• Noble gases

• Inert gases

• Unreactives

All noble gases have...

• 8 electrons in their outer shell

• properties similar to group 2 metals

• a full outer shell

• a different and distinctive colour

All group 8 elements are...

• monatomic gases

• colourless gases

• viscous gases

• flammable gaes

Group 0 elements show the following trends...

• They are more reactive down the group

• They are more reactive at the top of the group

• The melting point increases down the group

• The boiling point increases down the group

Group 0 elements are inert.This means....

• They are coloured

• They don't react

• They are all diatomic

• They are precise

Melting and boiling points increase down group 0 because...

• They are inert gases

• Group 0 elements are monatomic

• There are greater forces between the atoms

• There are more electrons in each atom

Argon is a gas aoom temperature (25'C). Name one other group 0 element that is also a gas at this temperature.

Krypton and Xenon have boiling points of -153'C and -108'C respectively. Suggest a value for the boiling point of Argon.

• 153'C

• 25'C

• -62'C

• -110'C
