First, let's have a look at all the clues in the name. Aromatic - this type of reaction is characteristic for aromatic compounds because it involves the aromatic ring. It is the only type of electrophilic...

As we move across the period electrons occupy the same outer electron shell, having roughly the same distance to the nucleus. Moving across the period nuclear charge increases as the number of protons in ...

Magnesium atoms lose two electrons from its outer shell, thus form positvely charged ions with a charge of 2+. These 2 electrons are transferred to and gained by a diatomic molecule of chlorine atoms - ea...

It is a giant lattice structure. Sodium ions (Na+) are positively charged and chloride ions (Cl-) are negatively charged. There is ionic bonding between - strong electrosatic forces of attraction between ...

Part 1: "A salt is is when the H⁺  ion in an acid is replaced with a cation (e.g. a metal)" 

Part 2: You would use the silver nitrate test for halide ions. You add dilute nitri...
