Group 7 (Halogens) Displacement Reactions - GCSE Chemistry | kayscience.com

The more reactive halogen will displace a less reactive halogen from the salt. The halogen is dissolved in water where chlorine is pale green, bromine is yellow, and iodine is dark red-brown. The halide salt solution is always colourless. The less reactive halogen left in the solution controls the colour. Group 7 elements are known as halogens. They are in group 7 so have 7 electrons in their outer shell. They share their outer electron with another atom of the same element to achieve a full outer shell. Halogens can form diatomic molecules which are two atoms covalently bonded together. The covalent bonds between the atoms are strong, and there are weak intermolecular forces between the molecules.

In my textbook, Fluorine is pale green, Chlorine is yellow green, Bromine is red black, Iodine is grey black and Astatine is black.

How do you write the word equations for group 7 elements

[queenofcrafts]

Your video is good but your colors are different than the Exam marking scheme.

You messed up those last two answers in this video also.

Why displacement reaction of halogens are not taken in aqueous solution ????
