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
