Going down the group, the softness of the elements___
increases
decreases
remains the same
Select the correct statement(s) that describe physical properties of Group 1 elements:
Soft metals
High density
Floats on the surface of water
Shiny silvery surface but tarnish quickly in the air
Needs to be stored under paraffin oil
Going down Group 1, the melting point and boiling points ____
increases
decreases
remains the same
Select the correct statement that explain the trend of melting point and boiling point going down Group 1 elements:
Atomic radius increases causing the metallic bond between atoms become stronger; more energy is required to overcome the stronger forces of attraction
Atomic radius increases causing the metallic bond between atoms become weaker; less energy is required to overcome the weaker forces of attraction
Atomic radius decreases causing the metallic bond between atoms become stronger; more energy is required to overcome the stronger forces of attraction
Atomic radius decreases causing the metallic bond between atoms become weaker; less energy is required to overcome the weaker forces of attraction
In general, the melting point and boiling points of Group 1 elements are
high
low
not too high and not too low
