Are ions of alkali metals larger or smaller than ions of alkaline earth metals from the same period?
larger
Alkali metals alkaline earth metals and aluminum all form ions with postivie charges equal to the?
the group number
Why Alkaline earth metals are harder than alkali metals?
It is because alkali metals are larger in size than alkaline earth metals.Also, the effective nuclear charge is more in case of alkaline earth metals. This makes their ionization enthalpies larger than alkali metals.
Do alkaline earth metals form ions with a plus 2 charge?
YEP! remember In science in order for the Alkali metals and Alkaline earth metals to become stable they must give AWAY electrons. The Earth metals have a Plus 2 charge because they give away 2 electrons on there outer shell!
Are Alkaline Earth Metals Cation ions?
Alkaline Earth metals are the elements in group 2 of the periodic table. They include beryllium, magnesium, calcium, strontium and barium. Radium is unstable as it is radioactive.
Is it possible for alkaline earth metals to form M 1 ions?
No, alkaline earth metals typically form M^2+ ions, not M^1+ ions. This is because they have two valence electrons that are easily lost to achieve a stable electron configuration.
How does the total mass percentage of alkaline earth metal ions compare with the total mass percentage of alkaline metal ions?
The total mass percentage of alkaline earth metal ions is higher than that of alkaline metal ions in a compound since alkaline earth metals have a higher atomic mass compared to alkali metals. This means that alkaline earth metals contribute more to the total mass of the compound when present as ions.
What is the charge on alkaline-earth metal ions?
Alkaline-earth metal ions typically have a charge of +2. This is because they lose two electrons to achieve a stable electron configuration, resulting in a 2+ charge. Examples of alkaline-earth metals include calcium (Ca2+), magnesium (Mg2+), and barium (Ba2+).
Are ions of alkali metals larger or smallest than ions of alkaline earth metals from the same period?
Ions of alkali metals are generally larger than ions of alkaline earth metals from the same period because alkali metals have only one outer electron, leading to a larger atomic radius and therefore a larger ion size compared to alkaline earth metals, which have two outer electrons.
Are ions of alkali metals larger or smaller than ions of alkaline earth metals from the same period?
larger
Are ions of alkali metals larger or smaller than ions or alkaline earth metals from the same period?
larger
What is the charge on alkaline earth metal ions?
Alkaline earth metal ions typically have a charge of +2. This is because they lose two electrons to achieve a stable electron configuration similar to that of noble gases. Examples of alkaline earth metals include calcium (Ca2+), magnesium (Mg2+), and barium (Ba2+).
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 2 groups of metals are the most reactive?
Alkali metals (Group 1) and alkaline earth metals (Group 2) are the most reactive groups of metals. They readily lose electrons to form ions and participate in chemical reactions with nonmetals to achieve a stable electron configuration.
What are the differences between alkali metals and alkaline earth metals in terms of their properties and reactivity?
Alkali metals and alkaline earth metals are both groups of elements on the periodic table, but they have distinct differences in their properties and reactivity. Alkali metals are located in Group 1 of the periodic table and are highly reactive, soft metals that easily lose their outermost electron to form positive ions. In contrast, alkaline earth metals are located in Group 2 and are less reactive than alkali metals, but still have a tendency to lose electrons to form positive ions. Alkaline earth metals are harder and have higher melting points compared to alkali metals. Overall, alkali metals are more reactive and have lower melting points than alkaline earth metals.
Which group most commonly forms 2-ions?
Group 2 elements (alkaline earth metals) commonly form 2+ ions by losing two electrons to achieve a stable noble gas configuration.
