Is ca plus 2 or mg plus 2 larger?
The Ca2+ ion is larger than the Mg2+ ion. The ionic radii are: 86pm for the Mg2+ and 114pm for the Ca2+. Besides the fact that the Ca2+ has more electrons this can be explained by the principle of electron shielding. Electron shielding is when lower level electrons block the EFC(effective nuclear charge) from effecting the valence electrons of an ion. Ca2+has more electrons than Mg2+ so more electron shielding occurs.
What reagent is used to separate Na and Mg2?
Na+ and Mg2+ can be separated by adding CO32- ions to the solution, forming MgCO3 precipitate which can be filtered off.
What ions are filtered and exchanged in the kidney tubules?
Sodium (Na+) Potassium (K+) Chloride (Cl-) Bicarbonate (HCO3-) Hydrogen (H+) Calcium (Ca2+) Magnesium (Mg2+)
Ions of calcium fluorine magnesium and iodine have electron configurations that are similar to which noble gases?
Ca2+ is isoelectronic with the noble gas, Argon. F-, Mg2+ are isoelectronic with the noble gas, Neon. I- is isoelectronic with the noble gas, Xenon
What is the average hardness of a bottle of water?
Total hardness=(Ca2+)*(combining weight of CaCO3/combining weight of Ca2+) +(Mg2+)(combining weight of CaCO3/combining weight of Mg2+)
What can ions be broken into?
I think you may asking about Ca2+, Mg2+.Na+ , etc..Isnt it? I think think they can be separated to Atoms & electrons. Like this Mg2+ Separate as Magnesium Atom & 2 electrons
What are cations?
Cations are positively charged ions. •Na+ •K+ •Ca2+ •Mg2+
What two elments have ions with a 2 charge?
Mg2+ and Ca2+ (and many more!)

What is the element that binds to troponin?
Ca2+ , Mg2+ .
Which ion has the smallest ionic radius Mg2 plus or Ca2 plus?
Mg is in period 3. Ca is in period 4. Down a group the size increases. So Mg is smaller than Ca.

When an atom becomes on ion with a two-charge the atom?
The group 2 elements form ions with a 2+ charge. For example, Mg2+ and Ca2+. The group 16 elements form ions with a 2- charge. For example, O2- and S2-.
Equation showing the formation of scum when soaps are dissolved in hard water?
Sodium Stearate + Ca2+ and Mg2+ = Calcium Stearate + Na+ Ions (Soap) (Dissolved in water) (Soluble in water)
