Size, magnetism, and solubility
Periodic table help to estimate the chemical and physical properties of elements.
Size and shape. However, chemical properties are usually more important.
This is possible because components of a mixture haven't chemical bonds between them.
Periodic table determine chemical properties. It later helps in predicting the bonds formed by elements.
There is a big difference between Non-metallic minerals and metallic minerals.Metallic minerals are composed primarily of metallic elements and have a metallic lustre and other properties, such as the ability to conduct electricity. Non-metallic minerals do not have these characteristics
When elements combine, the resulting compound is usually very different to the original elements. Take common salt for example. Sodium and chlorine are very reactive elements that you certainly would not allow anywhere near your food, yet sodium chloride is an essential part of our diets.
Metallic Bonds
It would be a good conductor. With bonds that explain gold's properties
Freely moving electrons.
Place the mixture in water. You recover the iron once the salt dissolves. Then allow the water salt mixture to dry and allow salt crystals to reform.
well because of the free electrons in the structure of aluminium it is able to allow the passage of electron from electric current due to disassociated electrons in its structure basically because of the metallic bonding and the free electrons present it can conduct electricity and heat.
