How does the reactivity of an alkaline earth metal compare with that of alkali metal in the same period?
Alkaline earth metals are less reactive than alkali metals in the same period because they have higher ionization energies and are less likely to lose electrons. Alkali metals readily lose their outermost electron to form a +1 charge, whereas alkaline earth metals require more energy to lose their outermost two electrons to form a +2 charge.
What is the charge for the alkali earth metals?
The alkali earth metals have a charge of +2. This is because they have two valence electrons which they lose to form ions with a 2+ charge, making them more stable. Examples of alkali earth metals include magnesium, calcium, and strontium.
When alkali earth metals form ions what charge do they have?
Alkali earth metals typically form +2 ions when they lose two electrons to achieve a stable electron configuration (noble gas configuration).
Why are the alkaline-earth metals less reactive than the alkali metals?
Alkaline-earth metal have two electrons in there outer shell, so only need to lose one to form a stable electron arrangement. Alkali metals have one electron in there outer shell - so they need only lose one to form a stable electron arrangement
What would an alkaline earth metal do with electrons to become stable?
An alkaline earth metal would typically lose two electrons to become stable. This would result in the metal forming a 2+ cation, as it will have the same electron configuration as the nearest noble gas.
How does the reactivity of an alkaline earth metal compare with that of alkali metal in the same period?
Alkaline earth metals are less reactive than alkali metals in the same period because they have higher ionization energies and are less likely to lose electrons. Alkali metals readily lose their outermost electron to form a +1 charge, whereas alkaline earth metals require more energy to lose their outermost two electrons to form a +2 charge.
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.
Why alkali and alkaline metal are very reactive among periodic table?
Alkali metals and alkaline earth metals have 1 and 2 valence electrons respectively. If they lose these electrons, they will get the electronic configuration of the nearest noble gas (stable octet configuration) and hence they are very reactive.
Do alkali metals tend to gain or lose electrons?
Alkali metals tend to lose electrons in chemical reactions.
What happens to the electrons in the outer shell when the alkali metals react with other elements?
the alkali metals have 1 electron in their outer most shell. in order to obtain a full outer shell they have to lose this electron. so when they react with another metal they lose this electron and the outer most shell.
Which family of elements loses electrons most easily?
The alkali metal group easily lose their outermost electron. This group consists of lithium, sodium, potassium, rubidium, cesium, and francium.
Does cesium have high electronegativity?
Cesium has a low electronegativity because it is a highly reactive alkali metal. Alkali metals typically have low electronegativities due to their tendency to lose electrons easily.
Why amonia solution of alkali metals are blue in clour?
The blue color of alkali metal solutions is due to the formation of solvated electrons. When alkali metals dissolve in ammonia, they lose an electron to form free electrons that react with the solvent (ammonia) to create a blue color. This phenomenon is known as the formation of solvated electrons and is responsible for the blue color of the solution.
What is the charge for the alkali earth metals?
The alkali earth metals have a charge of +2. This is because they have two valence electrons which they lose to form ions with a 2+ charge, making them more stable. Examples of alkali earth metals include magnesium, calcium, and strontium.
When alkali earth metals form ions what charge do they have?
Alkali earth metals typically form +2 ions when they lose two electrons to achieve a stable electron configuration (noble gas configuration).
Is magnesium active or inactive?
Magnesium is an active element. It is a highly reactive alkali earth metal that readily forms compounds with other elements due to its tendency to lose electrons and achieve a stable electron configuration.
How many electrons is the alkali metal losing when it becomes an ion?
Alkali metals lose one electron when it becomes an ion.
