Groups in the periodic table

• Elements in the same group of the periodic table show trends in physical properties, such as boiling point.
• Elements in group 0 of the periodic table, named for their lack of chemical reactivity, exist as single atoms.
• Group 0 is located on the far right-hand side of the periodic table.
• The noble gases exhibit trends in their physical properties.
• A description of the appearance of a substance or how it acts without involving chemical reactions is known as physical properties.
• Boiling points are a characteristic of physical properties.
• The noble gases all have low boiling points.
• The temperature at which a substance rapidly changes from a liquid to a gas is known as boiling point.
• Helium, at the top of group 0, has the lowest boiling point of any element.
• The attractive forces between the atoms become stronger as you go down group 0.
• More energy is needed to overcome these forces as you go down group 0.
• The likely boiling point of radon can be predicted.
