Trends in groups and periods
General trends in groups
Trends in groups
Trends in group I
Reactivity increases as we go down the group
Melting points become lower as we go down the group
Densities increase as we go down the group
Trends in group 7
Reactivity decreases as we go down the group
Increase in boiling and melting point as we go down the group
Trends in group 8
Reactivity increases as we go down the group
Going down a group atomic size increases
Going down a group mettalic character increases
Going down reactivity of metals increases
General trends in periods
Moving left to right in a period the number of valence electrons increases from 1 to 8 except for the 1st period and for it the last element has 2 valence electrons
Moving from left to right the elements have consecutive atomic numbers
Moving left to right atomic size decreases
Moving left to right metallic character decreases
Chemical reactivity first decreases then increases moving from left to right
