What do an ion of Ca2 plus and an atom of Ar have in common?
They have the same number of electrons. A neutral Ca atom would have 20 electrons but because it is a Ca2+ ion it only has 18 electrons (the same as Ar).
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.
Which is not a polyatomic ion?
Ca2+
Is Ca2 plus likely to form How about Br- Ne- Ne plus?
Ca(2+) and Br- are common ions; the neon ion probable doesn't exist.
Does the Ca plus 2 ion have more electrons than the Ca atom?
No, Ca2+ has 2 electrons LESS than Ca
What is the name of the ion Ca2?
The symbol Ca2+ is for the cation of calcium.
The chemical symbol Ca2 plus refers to the?

What protein changes shape when ca2 plus binds to it?
The protein that changes shape when calcium ion (Ca2+) binds to it, is the troponin. It is a regulatory protein that is a component of the thin filament.
Which is not a polyatomic ion?
Ca2+
Is Ca2 plus a cation?
Yes it is a cation which is an ion with fewer electrons than protons, giving it a positive charge.
What ion form calcium?
Ca2+
