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 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 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 equation balance and identify the type of reaction of Ca Mg(NO3)2?
The balanced equation for Ca + Mg(NO3)2 would be Ca + Mg(NO3)2 -> Ca(NO3)2 + Mg. This is a double displacement reaction, where the calcium (Ca) and magnesium (Mg) ions switch places with the nitrate ions (NO3).
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
Which is larger 128 mg or 2 g?
Each g has 1,000 mg, so 2 g are definitely larger than only 128 mg.

Which atom is most likely to form a cation with a charge of plus 2?
An atom with two valence electrons, such as calcium (Ca), is most likely to form a cation with a charge of plus 2 by losing both electrons to achieve a stable octet configuration.
