Question

compare the following properties with reference to alkali metals and halogens.

1)electronic affinity
2)valency
3)ionisation energy
4)electronegatively
5)natur of oxides​

Answer 1

Answer:

1.electron affinity - low for alkali metals and high for halogens.

2. valency alkali metals 1 ND halogen -1

3. ionisosation energy - low for alkali metals and high for halogen.

4. electronegetivity - low for alkali metals and high for halogens

5 nature of oxides - electrovelent for alkali metals and co- velent for halogens
