What else can I help you with?
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 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.
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 is the formula for the ionic compounds formed by magnesium ions and calcium ions with nitrate ions?
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.
What is the electronic configuration of mg2 plus?
Mg2+: [1s22s22p6]
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!)

Which ion has the smallest ionic radius Mg2 plus or Ca2 plus?
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+.
Is ca plus 2 or mg plus 2 larger?

How does borax serves as water softening agent?
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+
What are the major ions in freshwater?
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.
What can you find dissolved in hard water?
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+)
