group 0 elements

• noble gases have a full outer shell meaning they are inert
• when you go down the group, the boiling points increase due to an increase in number of electrons in each atom leading to greater intermolecular forces which need to be overcome
• the boiling point increases as we move down the group because there is more energy needed to break the stronger bonds between atoms
• they are monatomic gases
• all noble gases are colourless at room temperature
