Differences and trends in the
properties of the elements
· The electronic structure of the
elements are the same leaving 1
electron on the outer shell.
· They are soft and shiny.
· As you go down the group melting
points and boiling points decrease.
· Rubidium and caesium sink because
their density is more than water.
· Energy needed to melt element
decreases as you go down the group.…read more
