Periodic Table
Group 7
Group 7 reactivity decrease, down the group
gain this electron gets easier as we go up the group
Group 7 have 7 valence electron
It's opposite way of Group 1
element gain electron but big ones cannot do this well -- they react slower
Group 1
Losing this electron gets easier as we go down the group
Group 1 have 1 valence electron at each element
Group1 reactivity increase, down the group
It's opposite way of Group 7
Atoms lose electrons so big element react faster
Group 6
Group 6 have 6 valence valence electron at each element
Group
group indicate the number of valence electron
Period
indicate the number of electron shells an element
Transition Metals
Big atom are not good at holding electron (the electron are far from the nucleus
