The properties of alkali earth metals and alkaline metals want to give up or share their valence electrons when bonding with a non-metal or polyatomic ion. For example, Sodium (Na) has a single valence electron, and if it bonds with Chlorine (Cl) which has seven valence electrons, Sodium would give up and share it's electron with Chlorine. Because an electron is negatively charged, and a proton, inside the nucleus, is positively charged, the Sodium atom has one less negative charge, and one more positive charge, rendering the ionic charge no longer neutral but +1. This is why metals are able to form cations.

Why Alkali metal and alkaline earth metal form cation?
alkaline earth metals and alkali metals have 2 and 1 electrons in their outer most shell and are not tightly bound to nucleus so they are ready to lose their outer most electrons to form mono and divalent cations.
How are alkali metals different from alkaline metals?
The alkali metals are generally more reactive than the alkaline earth metals. They form 1+ ions while the alkaline earth metals form 2+ ions. Alkali metal compounds tend to be more soluble in water than alkaline earth metals.
Which properties of alkali metals unusual metals?
Alkali metal forms Alkali while metals form bases.
What is the difference between alkali metals and alkali earth metals?
Alkali metals are from Group 1 of the Periodic table and have a single electron in their outer shell. Alkaline-Earth metals are in group 2 of the periodic table and have 2 electrons in their outer shell.
Why does lithium form stable complex compound than other alkali metals?
As complex comopunds or salts are those which can dissociate to give complex anion and simple cation and vice versa. As Li is small in size and if Li combine with comples anion then it will form a complex compounds.While the other alkali metals are large in size. So if these metals combine with large anion or complex anion then they does not form a complex compounds. It is the reason that Cation which is in the form of alkali is large or complex and anion also comple. So, in this case both ions that produced are large.That's why other then Li, alkali metals not form comples compounds. One of the best example of Li complex compound is " Lithium tetra-amine " Li(NH3)4

Do Alkali earth metals react with oxygen?
Alkali earth metals react with oxygen to form basic oxides.
How are alkali metals different from alkaline metals?
The alkali metals are generally more reactive than the alkaline earth metals. They form 1+ ions while the alkaline earth metals form 2+ ions. Alkali metal compounds tend to be more soluble in water than alkaline earth metals.
Is a metal an acid or alkali?
its definitley not acid Some metals are called alkali metals or alkaline earth metals because they often form alkaline compounds; but metals are not alkali or acids.
When alkali earth metals form ions what charge do they have?
The answer is 2+
Why do you think the most commonly used metal objects of transitional metals rather than alkali metals or alkaline earth metals?
Alkali and alkaline earth metals are too chemically reactive to stay in metallic form.
Do both alkali metals and alkaline earth metals form alkaline sollutions when mixed with water?
Yes, it is true.
Which properties of alkali metals unusual metals?
Alkali metal forms Alkali while metals form bases.
What ion will form from bromine atom?
Any metals in the reference table can form an ionic bond with a Br atom.For example, Lithium, Sodium and Calcium.
What type of ions do the alkali earth metals form?
Alkali metals, like all other metals, form positive ions. The atom, in order to achieve octet structure, loses the 1 valence electron to the environment. Thus, it will have 1 less electron than the element should, and as a result form a 1+ charged ion.
Why are neither the alkali metals nor the alkaline earth metals found in nature?
Because these metals are very reactive and readily form compounds.
Alkali metals alkaline earth metals and aluminum all form ions with postivie charges equal to the?
the group number
