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 metalsNonmetalsHalogens
Because halogens form negative ions, alkali metals form positive ions; both are reactive elements and an electrostatic attraction exist.
No single element can be both an alkali metal (form +1 cations) and a halogen (form -1 anions).Alkali metals :LithiumSodiumPotassiumRubidiumCesiumFranciumHalogens:FluorineChlorineBromineIodineAstatine
Potassium and sodium are both metals. They belong to the alkali metal group of the periodic table, which is known for its highly reactive properties.
Cesium and francium are the most reactive and lithium is the least. Because the reactivity of alkali metals increases going down the group. Down the group: atomic and ionic radii and density increase while melting and boiling points decrease. Therefore it is easy for them to lose the one electron on the outer orbital. So it is very reactive.

Sodium and Chlorine = Sodium Chloride Potassium and Iodine = Potassium Iodide
For example halogens easily react with alkali metals because both are very reactive; compounds are with ionic bonds.
Alkali metals have one electron in their valency shell whereas halogens have seven. By losing al electron to a halogen, both ions get a full set of electrons in their valency shell.
No, alkali metals are not the only earth metals. Earth metals include both alkali metals and alkaline earth metals. Alkaline earth metals are a group of elements in the periodic table that are chemically similar to, but less reactive than, alkali metals. Examples of alkaline earth metals include magnesium, calcium, and barium.

Well, the "happy" number in chemistry is eight. And alkali metals have one valence electron while halogens have seven so when they combine, the combination has eight valence electrons. This means it is full.
here r the possisble answers: both atoms lose 1 electron a covalent bond forms metal gains an electron and the nonmetal loses an electron metal loses an electron and non metal gains an electron
No, hydrogen is a nonmetal. It is grouped with the alkali metals because it has a similar outer shell electron configuration as they do. Hydrogen is something of an oddball among elements. It is rather unique, but share some characteristics with both the halogens and the alkali metals. When the periodic table is divided into groups (noble gasses, halogens, alkali metals, etc.) hydrogen is usually put in its own group.
