In terms of ion charges and chemical change, CuF ha +1 charge and CuF₂ has +2 charge. This is the difference between CuF(s) and CuF2(s).
An atom or molecule with a net electrical charge is known as an ion. Conventionally, the charge of an electron is thought to be negative; this charge is equal to and opposite to the charge of a proton, which is thought to be positive.
As stability depends on the hydration energy of the ions when they connect to the water molecules, Cu2+ is more stable than Cu+. Because the Cu2+ ion makes significantly stronger bonds and has a higher charge density than the Cu+ ion, it releases more energy.
Copper(I) ion is created when copper provides one electron to another atom; this accounts for the +1. Copper has one fewer electron than protons. Copper(II).
Thus, In terms of ion charges and chemical change, CuF ha +1 charge and CuF₂ has +2 charge.

When a calcium atom loses two electrons, it becomes positively charged because it has more protons than electrons. In this case, since two electrons are lost, the calcium ion has a charge of +2.
When an atom loses or gains electrons, it undergoes a process called ionization, resulting in the formation of an ion. In the case of calcium (Ca), it typically loses two electrons to achieve a more stable electron configuration.
A neutral calcium atom has 20 electrons, with the electronic configuration 1s² 2s² 2p⁶ 3s² 3p⁶ 4s². By losing its two outermost electrons from the 4s orbital, it forms a calcium ion (Ca²⁺) with 18 electrons.
The loss of two negatively charged electrons leaves the calcium ion with a net positive charge. The charge on an ion is indicated by a superscript after the ion symbol. In this case, the superscript is +2, denoting that the calcium ion has a charge of +2.
Hence, the correct answer is +2.
