Question

What happens when alkali metal reacts with
halogens
with the equation​

Answer 1

Answer:

When the alkali metals react with the different halogens (Group 7 of the periodic table), the group of compounds formed are known as the alkali metals halides. Due to the fact that there are a number of different halogens that can react with the alkali metals, you must be prepared to change the halide involved depending on the question being asked.

All alkali metal halides are white solids.

Note that all the halogens are toxic, and so these reactions should be carried out in a fume cupboard.

Lithium

lithium + [halogen] → lithium [halide]

Answer 2

Answer:

All the alkali metals react vigorously with halogens to produce salts, the most industrially important of which are NaCl and KCl. Sodium Chloride is used as a preservative for meat and to melt the ice on the roads (via freezing point depression).
