Alkalis are defined as alkalis because the have a high pH (hydrogen potential). This means they are willing to accept hydrogen ions and therefore give off electrons. Halogens are defined as halogens because they are in group seven of the periodic table which means they are missing one electron from their outer shell. Alkalis react well with halogens because of alkalis wanting to give away electrons and halogens wanting to accept electrons, forming ionic bonds.

Alkali metals have one electron in their outer shell that they want to lose, while halogens have seven electrons in their outer shell and want to gain one electron to complete their octet. When an alkali metal reacts with a halogen, the alkali metal readily gives up its electron to the halogen, forming an ionic bond between the two ions. This transfer of electrons provides stability for both elements, leading to the reaction.

What elements react the best with the alkali metals?

Non metals form ionic bonds with metals. Non metals gain the electrons while metals loose. Alkali metals reacts with halogen family in efficient manner.

Does CaCl2 contain an alkali metal and a halogen?

Calcium chloride contains an alkali earth metal (calcium, a group 2 element) and a halogen (chlorine). There is no alkali metal. Alkali metals are group 1 elements.

How do the chemical properties of the alkali metals and halogens that react to form them?

Alkali metals, like sodium and potassium, have one valence electron and readily lose it to form a +1 cation. Halogens, like chlorine and fluorine, have seven valence electrons and readily gain one electron to form a -1 anion. When alkali metals react with halogens, the alkali metal donates its electron to the halogen, forming an ionic compound.


Is K a halogen?

NO"!! K is potassium ( Latin ; Kalium). It is a Group (I) Alkali Metal.


Is fluorine an alkali?

NO!!!! Fluorine is an elemental gas in the HALOGEN Group. The word 'halogen' is from Latin and means 'salt maker'. So when fluorine is combined with a Group (I) or (II) metal (Alkali/Alkali Earth Metal) ot forms a salt. e.g. 2Na(s) + F^(2)(g) = 2NaF(s) ( The chemical salt).
