What trends in the solubilities of the compounds of the alkaline earth metals can be inferred?
1) NaOH : two top alkaline earth metals' solubility is decreasing as we can see from cloudy to lots of solid and two bottom metals' solubility is also decreasing in observing difference amount of solid between Sr(NO3)2 and Ba(NO3)2 2) NaCl: all of the alkaline earth metals are soluble. 3) NABr: all of the alkaline earth metals are soluble. 4) NaI: all of the alkaline earth metals are soluble. 5) Na2SO4: solubility of alkaline earth metals is decreasing from clear to solid and cloudy. 6) Na2CO3: solubility of alkaline earth metals from Mg(No3)2 to Sr(NO3)2 is decreasing and after Sr(NO3)2, solubility is increasing. 7) Na2C2O4: solubility of alkaline earth metals is decreasing from clear to solid and cloudy.
Why Solubility of alkali metal carbonates increases down the group but for alkaline earth metals decreases down the group?
as we move down the group solubility of sulphates decrease,for alkaline earth metals because down the group, size of cation increase, thus hydration energy decreases,and thus solubility of sulphates decrease.
Where are alkaline earth metals located on the periodic table?
2A Starting with beryllium and heading down to the bottom of the column.
Compare the solubilities of the lead compounds with those of the alkaline earth metals How are the solubilities similar and different?
Look at the position of Pb in the periodic table and the postion of the Alkali Earth metals. Alkali Earth Metals are in noble-gas configuration when they are doubly charged cations. Lead however is on the right hand side, and would like to have more electrons to get into that stablest configuration; making the bonds in lead-compounds more covalent -and stronger- in nature. Insoluble compounds have lattice enthalpies higher than the enthalpy of solvation. Now since Alkali Earth metals like to be in ionic states; their compounds will dissolve in general more easily than the same compounds with lead, since usually the lattice energy of lead compounds is much higher (In case of insoluble compounds higher than the energy that would be released upon solvation, which thus doesn't occur).
Is the alkali metal more reactive than an alkaline-earth metal?
Yes, alkali metals are more reactive than alkaline-earth metals. All atoms want to have 8 electrons in their outer shells. Alkali metals have to give one electron away, where as alkaline-earth metals need to give two away which is less energetically favorable.

Electronegativity increases from left to right and _ bottom on the periodic table from top to?
Electronegativity increases from left to right and decreases from top to bottom on the periodic table.
What happens to the amount of biomass from the bottom to the top of the pyramid?
it decreases.
What will appear at the bottom of the solution if you lower the temperature if a saturated solution?
If you lower the temperature of a saturated solution, some of the solute may begin to precipitate out of the solution and settle at the bottom. This is because solubility generally decreases with decreasing temperature, so the excess solute that was dissolved at the higher temperature will no longer be able to remain in solution at the lower temperature.
How can you tell when you reach the solubility of salt in water?
You reach the solubility of salt in water when the salt stops dissolving and settles at the bottom, no matter how hard you try to mix it. You can increase solubility by increasing the water temperature.
As you move from the bottom of the periodic table to the top shielding increases or decreases?
decreases
What is the trend in electron affinity of elements within a group?
decreases from top to bottom
Electronegativy from top to bottom on the periodic table?
Electronegativity generally decreases from top to bottom on the periodic table. This is because as you move down a group, the valence electrons are in higher energy levels, farther away from the nucleus, which reduces the attraction for additional electrons.
What happens to the atomic radius as you from the bottom to the top of the periodic table?
The atomic radius decreases.
Does the first ionization energy increase or decrease from top to bottom in periodic table for the alkali metal family?
The first ionization energy generally decreases from top to bottom in the alkali metal family. This is due to the increase in atomic size and the shielding effect from inner electrons, which makes it easier to remove the outermost electron.
What are two trends in the periodic table?
Atomic size decreases from left to right in a period hence ioniztion energy increases from left to right.But atomic size increases from top to bottom in a group hence ionization energy decreases from top to bottom.
