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 kind of reaction is this Mg plus 2AgCl 2Ag plus MgCl2?
Calcium(Ca), being a more reactive element, reacts with FeCl3 to produce CaCl2 and Iron(Fe).3 Ca + 2 FeCl3 ----> 3 CaCl2 + 2Fe
What is the single replacement reaction for Ca plus H2O?
CrCl6(AQ) + Mg(S) -> MgCl2(AQ) + Cr(S) CrCl6(AQ) + 3Mg(S) -> 3MgCl2(AQ) + Cr(S) Make sure both sides are balanced. The 3 in front of both of the Mg's is be cause 3*2=6, and you have to put a 3 in front to balance it out with the CrCl6,and the Mg's need to be balanced too so you another 3 in front of the Mg. Now the reaction is balanced.
In the reaction mgcl2 plus 2koh mg(oh)2 plus 2kcl How many moles are of mg(oh)2 are produced for every mole of mgcl2?

What is the equation balance and identify the type of reaction of Ca Mg(NO3)2?
Ca + Mg(NO3)2 --> Ca(NO3)2 + Mg This is a single replacement reaction.
Which atom is most likely to form a cation with a charge of plus 2?
Magnesium (Mg)
Which is larger 128 mg or 2 g?
Each g has 1,000 mg, so 2 g are definitely larger than only 128 mg.
What are the products when i react Mg plus NaOH Al plus NaOH and Ca plus NaOH I need to know what they producce and i can't figure it out Net ionic's would be great too but i can figure those out.?
2 Mg + 2 NaOH-------2 MgO + H2 + 2 Na 2 Al + 6 NaOH------2 Na3AlO3 + 3 H2
What kind of reaction is this Mg plus 2AgCl 2Ag plus MgCl2?
Calcium(Ca), being a more reactive element, reacts with FeCl3 to produce CaCl2 and Iron(Fe).3 Ca + 2 FeCl3 ----> 3 CaCl2 + 2Fe
Net inonic equation for Mg plus CuCl2 equals MgCl2 plus Cu?
mg + CuCl2 + MgCl2 + Cu Mg + Cu^+2 = Mg^+2 + Cu
What is larger 200 mg or 1 g?
200 mg is 2 g

5.50
What is Enchange reaction?
2CaCO3+Mg^2+--> CaMg(CO3)2+Ca^2+
What is the single replacement reaction for Ca plus H2O?
CrCl6(AQ) + Mg(S) -> MgCl2(AQ) + Cr(S) CrCl6(AQ) + 3Mg(S) -> 3MgCl2(AQ) + Cr(S) Make sure both sides are balanced. The 3 in front of both of the Mg's is be cause 3*2=6, and you have to put a 3 in front to balance it out with the CrCl6,and the Mg's need to be balanced too so you another 3 in front of the Mg. Now the reaction is balanced.
What is the chemical change in the following reaction Mg(NO3)2 plus 2NaOH Mg(OH)2 plus 2NaNO3?
The chemical equation is:Mg(NO3)2 + 2 NaOH = Mg(OH)2(s)+ 2 NaNO3
