Why HYDROGEN is not included in alkali metals although it appears to be listed in Group 1?
Group 1 elements are soft metals with low densities and low melting points as compared to other metals such as iron and copper. they have silvery and shiny surfaces. they are also good conductors of heat and electricity.
Group 1 elements are soft metals with low densities and low melting points as compared to other metals such as iron and copper. they have silvery and shiny surfaces. they are also good conductors of heat and electricity.
When going down the group, the hardness, melting point and boiling point decrease.
When going down the group, the atomic size increases.
