Yeah - its in the second group of the periodic table therefore the ion will be 2+
Some more information which may aid understanding or may just be useful at some stage
An atom in group one will have an ion which is +1
An atom in group 7 will have an ion which is -1
An atom in group 6 will have an ion which is -2
They are the general rules for all the ions which you you will probably come across most often

Calcium is in group 2 therefore it needs to lose 2 electrons to achieve a noble gas configuration. The relative formula for a Calcium ion is therefore Ca 2+

The Calcium Ion is several to CA1+;
The counter ion of Calcium, experimental chart.
Calcium ++ and ii are non charged.
Ca ++ is probably potassium
Ca +2 and Ca 2+ are charged.
The MeV scale is only available with fusion or fission to something else.
Answer : 2+ charge.

+2, alkaline earth metal (or group two element if you like).
alkali metals bear +1 charge; alkaline earth metals bear +2 charge; Halogen mostly likely bears -1 charges.
General trends, nothing to it, so just straight forward memorization.
Plz remember, the charges for halogens and chalcogens (oxygen group) is not necessarily to be -1 or -2. Most obvious one is that oxygen bears -1 in hydrogen peroxide. Both of halogens and chalcogens can and will bear positive in some compounds (interhalogen for example).

It's a group 2 element (alkaline earth) so it has two "s" electrons that it's willing to get rid of. Therefore, it's a 2+ ion.

it's in the second column, which means it has to "give away" two electrons, and when you give away electrons, it makes the atom have a positive charge because electrons are negative. So the charge would be +2

Ca ---> Ca2+ + 2e-
It will lose 2 electrons to form the stable octet structure.

Electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2, so it will lose the two 4s electrons to become isoelectronic with argon. So, Ca2+.
