The Periodic Table Flashcards
Reactive pattern
Atoms with more electrons are more reactive
Group 1 elements
One electron on their outer shell
Alkali metals reactivity
Further down the group the metals are more reactive
Metals in group 1
Lithium Sodium Potassium Rubidium Caesium Francium
Hardness of metals in group 1
Softer further down
Density of metals in group 1
More dense as you go down apart from one element
Atomic size in halogens
Increases downward
Halogens
Fluorine
Chlorine
Bromine
Iodine
Density of halogens
Increases downward
What group are the halogens
Group 7
Reality of halogens
Decreases downward
Electronic configuration of halogens
Diatomic
Halogen + metal
Halide
Displacement reaction
A more reactive halogen will displace a less reactive halide from its compound in a solution
Example of displacement reaction
Chlorine+sodium bromide –> sodium chloride + bromine
