Answer
Below table shows the comparison of the elements of group 1[IA] i.e. alkali metals and group 17 [VIIA] i.e., halogens:
| Property | Group 1[IA] | Group 17 [VIIA] |
|---|---|---|
| Elements | Li, Na, K, Rb, Cs, Fr | F, Cl, Br, I, At |
| Valency | Univalent (1 valence electron) | Univalent (7 valence electrons) |
| Nature | Highly reactive, highly electropositive, light soft metals | Highly reactive, highly electronegative, non - metals |
| Conductivity | Good conductors of heat and electricity | Bad or non conductors of heat and electricity |
| Reducing / Oxidizing nature | Strong reducing agents | Strong oxidizing agents |
| Electronegativity | Low electronegativity | High electronegativity |
