Electronic structure and the periodic table

1. Lithium, Sodium and Potassium all belong to group 1
2. They will all have one electron in the outer shell since they are in group
3. Fluorine and chlorine, both belong to group 17
4. They have 7 electrons in their outer shell meaning the element is very reactive. It is very reactive because it has to only gain 1 electron for it to react.
5. Sodium, Magnesium and Sulphur all belong to period 3
6. They all belong to period 3 meaning they have 3 electron shells.
7. The metal property, “Malleable” means that that they can be manipulated and moulded into different shapes. The other property “Ductile” means that the metal can be stretched out into thin strands, such as wires
8. For a fluorine atom reacts, it only needs to gain 2 electrons to fill the second electron shell
