The cation Ca(2+) exist in many compounds, for example in salts.
Ca(2+) and Br- are common ions; the neon ion probable doesn't exist.
The charge of Ca2+ is correct. Calcium typically oxidizes to form a 2+ cation by losing two electrons.
In this reaction, Ca2+ reacts with NO2^1- to form Ca(NO2)2. The balanced chemical equation for this reaction is: Ca2+ + 2NO2^- → Ca(NO2)2.
Ca refers to calcium, which is a chemical element with the atomic number 20. Ca2+ refers to a calcium ion that has lost two electrons, resulting in a 2+ charge. The main difference is that Ca represents the neutral form of calcium, while Ca2+ represents the positively charged ion form.
An ion of Ca2+ would most likely ionically bond with an ion of O2- in a 1:1 ratio to form CaO (calcium oxide). Calcium typically bonds with oxygen to form stable ionic compounds due to their opposite charges.
Ca2+
The ionic compound formed by Ca2+ and F- ions is calcium fluoride.
An isotope of calcium

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
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 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.
