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).

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 plus?
Ca2+ is a cation formed by Calcium to become stable and attain the noble gas configuration of Argon. Calcium forms this cation by losing two electrons
How many electrons are in a calcium atom and in a calcium ion?
Calcium atom 20 e- Ca2+ 18 e-
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.
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.
What is the name of the ion formed by a calcium atom?
caltribadium ion
Does the Ca plus 2 ion have more electrons than the Ca atom?

What does a fluoride ion have in common with a neon atom and a sodium atom?
what does an atom have in common with an ion?
What does the symbol Ca2 plus represent?
Its a positive calcium ion that loses two electrons.
What is the negative charge of Ion?
An ion exists as an atom or a molecule where the total number of protons in the nuclei do not equal the atom/molecule's electrons. An example is Ca2+. It has 2 less electrons than it has protons.
What is the meaning of negatively charged ion?
An ion exists as an atom or a molecule where the total number of protons in the nuclei do not equal the atom/molecule's electrons. An example is Ca2+. It has 2 less electrons than it has protons.
How do you write the positive ion and negative ion for CaS?
Ca2+ and S2-
