Mg is in period 3. Ca is in period 4. Down a group the size increases. So Mg is smaller than Ca.
The ionic compound formed by Ca2+ and F- ions is calcium fluoride.
The balanced molecular equation is CaCl2 + Na2S -> CaS + 2NaCl. To write the ionic equation, we need to break down the reactants and products into their respective ions. This results in the ionic equation: Ca2+ + 2Cl- + 2Na+ + S2- -> CaS + 2Na+ + 2Cl-. Cross out spectator ions that appear on both sides of the equation to obtain the net ionic equation: Ca2+ + S2- -> CaS.
The net ionic equation is: Ca2+ (aq) + 2Ag+ (aq) → Ca2+ (aq) + 2Ag (s)
The ionic formula for Ca2+ and S2- is CaS, which is calcium sulfide. In this compound, calcium donates two electrons to sulfur, forming a ionic bond between the two elements.
The formula for the ionic compound formed by calcium (Ca2+) and bromine (Br-) would be CaBr2. The calcium ion has a charge of 2+ while the bromine ion has a charge of 1-, so two bromine ions are needed to balance the charge of one calcium ion.
I would not think so as their natural state radius is so close. Ca(2+) loses two electrons, so I think it would have the smaller ionic radius.
The ionic compound formed by Ca2+ and F- ions is calcium fluoride.
The particle Ca2+ is bigger in size compared to the Ca particle. This is because Ca2+ has an additional charge compared to Ca, which results in a larger ionic radius due to increased electron-electron repulsion that can overcome the attractive force between the nucleus and electrons.

The net ionic equation is: Ca2+ (aq) + 2Ag+ (aq) → Ca2+ (aq) + 2Ag (s)
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.

If you mean Ca3P2, this is calcium phosphide.
