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.

S2- Cl1- K1 plus and Ca2 plus are all with Ar?
They have the same electron configuration as argon, which means they are isoelectronic with argon.
In chemical notation Ca2 plus means what?
calcium ions that has lost electrons. It will give away electrons.

Which is more reactive Mg or Ca Why?
Calcium is more reactive. In the periodic table, Calcium is directly below Magnesium, which means that a calcium atom is larger than a magnesium atom. This means that the electrostatic attraction between the valence electrons of calcium and the nucleus is weaker than in magnesium(larger distance, smaller force). So, the valence electrons of calcium can easily be lost to form Ca2+ , which translates to Calcium being the more reactive metal.
What is the difference between a mmol and a mEq?
Milli equivalents and milli moles are units used to describe molecular or ionic grades of concentration. A milli equivalent or mEq is derived by dividing the concentration in millimol or mmol by the valency of the ion involved.Eg: 1 mEq of sodium Na+ = 1 mmol of sodium (because valency is 1)whereas 1 mEq of Ca2+ = .5 mmol of calcium. (because valency is
Li or Ca2 which cation is smaller?
Li+ is smaller than Ca2+
Which ion has the smallest ionic radius Mg2 plus or Ca2 plus?
Mg is in period 3. Ca is in period 4. Down a group the size increases. So Mg is smaller than Ca.
Which particle is bigger Ca or Ca2 plus?
Ca2 is basically two Ca's so it's larger (the plus doesn't compensate)
Does the Ca plus 2 ion have more electrons than the Ca atom?
No, Ca2+ has 2 electrons LESS than Ca
Is Ca2 plus a cation?
Yes it is a cation which is an ion with fewer electrons than protons, giving it a positive charge.
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.
How many electron ca2 plus?
Calcium has atomic number 20. A neutron calcium atom therefore has 20 protons and 20 electrons. Ca2+ has a charge of positive 2, so it must have 2 more protons than electrons. Ca2+ has 18 electrons.
What is the formula for the ionic compound Ca2 plus and Br?
Ca2+ and Br- obviously must form, CaBr2 Calcium bromide
The chemical symbol Ca2 plus refers to?
An isotope of calcium
The chemical symbol Ca2 plus refers to the?
Calcium Ion
Ca2 plus ions separate from Mg2 plus ions?
they cannot bond together, they are separate .
How many centimoles of charge of Ca2 plus are needed to replace 2 centimoles Na plus?
