Barium (137.327) is larger than aluminum (24.305)
population control!! dont take the any supplements with barium, fluoride or aluminum
Sr
No, they are not. That is a baseless and rather foolish rumor, no truth to it.
No. Aluminum oxide is a solid. In fact it is one of the hardest known substances.
Strontium
Barium is smaller than Cesium
The electronegativity of barium is less than that of strontium.
a general answer is that if it is a cation the ion is smaller than the atom due to loosing one or more electrons which would decrease the size of the radius anions are larger because they are gaining more electrons and electron electron repulsion is greater which spreads the anion apart
Many are thereSuch as Sodium, Potassium, Barium, Calcium, Magnesiumetc.
As beryllium is smaller than barium and it is more polarising, it will distort the perfect ionic sphere and attract some outer shell electrons of barium and give it a covalent character.

Any reaction occur.
Sr
Sodium ion is more hydrated than barium ion hence ionic mobility is less. Note that smaller ions with greater charge density gets more hydrated
Beryllium is more electronegative than barium. Elecronegativity decreases as you move down the periods of the periodic table. Since Ba is further down the table than Be in the same group, Be would be more electronegative.
Magnesium's atomic radius is smaller than Calcium's.
Element M can be a choice of 4 elements, Beryllium, Magnesium, Calcium, or Strontium. The element must have an oxidation of +2, which means group 2 elements. The atomic radius of a barium atom is 222pm. Radium has a larger atomic radius that Barium, so that is eliminated, and Barium is the same as Barium so that is also eliminated.
