Reactions
Reaction with Metals
Halogens react with metals to form salts called metal halides.
Reaction with Non-metals
Halogens react with hydrogen and other non-metals to produce covalent compounds.
Reaction with Alkali metals and alkaline earth metals
All alkali metals react with halogens to produce salts.
Alkaline earth metals react with halogens to form hydrated halides.
Halogens react with metals to form salts called metal halides.
- For example aluminum reacts with fluorine to make aluminum fluoride. This reaction can be shown by the equation 2Al(s) + 3F2(g) --> 2AlF3(s)
Reaction with Non-metals
Halogens react with hydrogen and other non-metals to produce covalent compounds.
- For example hydrogen and chlorine form hydrogen chloride, H2(g) + Cl2(g) --> HCl(l)
Reaction with Alkali metals and alkaline earth metals
All alkali metals react with halogens to produce salts.
- For example NaCl can be produced: 2Na(s) + Cl2(g) --> 2NaCl(s)
Alkaline earth metals react with halogens to form hydrated halides.
- The general equation can be given by M + X2 --> MX2 where M is the alkaline earth metal and X represents a halogen
