they cannot bond together, they are separate .
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
Na+ and Mg2+ can be separated by adding CO32- ions to the solution, forming MgCO3 precipitate which can be filtered off.
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.
The formula for the ionic compound formed by magnesium ions (Mg2+) and nitrate ions (NO3-) is Mg(NO3)2. The formula for the ionic compound formed by calcium ions (Ca2+) and nitrate ions (NO3-) is Ca(NO3)2.
Mg2+: [1s22s22p6]
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
Cations are positively charged ions. •Na+ •K+ •Ca2+ •Mg2+

Mg2+ has the smaller ionic radius compared to Ca2+ because as you move down a group in the periodic table, the ionic radius increases due to the addition of electron shells. Mg and Ca are in the same group, but Ca has more electron shells than Mg, resulting in a larger ionic radius for Ca2+.

When Borax is added to water, it reacts with Ca2+ and Mg2+, which come out of water as precipitates. The reactions involved are: Ca2+ + Na2B4O7 ----> CaB4O7 + 2Na+ Mg2+ + Na2B4O7 -----> MgB4O7 + 2Na+
The major ions in freshwater typically include calcium (Ca2+), magnesium (Mg2+), sodium (Na+), potassium (K+), bicarbonate (HCO3-), sulfate (SO42-), and chloride (Cl-). These ions contribute to the overall composition and chemistry of freshwater bodies.
Hardness of water is defined by its content of [Metal]2+ and M3+ ions that will precipitate in alkali (OH-) or with (bi)carbonate when heated above 60oC. Most common ions Ca2+, Mg2+, (Mn2+ and Fe2+,3+)
