No element is a member of both the halogens and the alkali metals. Hydrogen shares some properties of the two groups, but belongs to neither. It is instead in a group all its own.
Alkali Metals Alkaline Earth Metals Transition Metals / Metalloids (d group) Halogens Noble Gases
The basic famillies are - Group 1 the alkali metals. Group 2 the alkali earth metals Group 7 the halogens Group 0 or 8 (depending on your periodic table) are the noble gases.
The alkali metals are the most reactive of all groups on the periodic table. Some of the metals are lithium, potassium and sodium.
calcium is an alkaline earth metal thus has different characteristics to the alkali metals.
The most active metals are alkali metals.The most active nonmetals are halogens.
I think alkali is the most reactive one.
Base
Alkali stands for a chemical compound that neutralizes with acid and turns litmus blue and release hydroxide ions when dissolved in water. Alkaline has the properties of alkali or containing alkali and having pH greater than 7.
The term refers to properties of a base.

Metals - especailly alkali and alkaline earths, and halogens.
An ionic bond is formed by electron transfer between alkali metals and halogens.

alkali metals
Alkali metals , alkaline earth metals and halogens are most important ionic compound former .
they are harder than alkali metals
