Chlorine gain electrons.
A chlorine atom would gain one electron to become an ion because it tends to achieve a stable electron configuration by having a full outer shell of electrons.
Chlorine will gain electrons in the reaction with calcium. Chlorine is a halogen, which tends to gain an electron to achieve a full outer shell, while calcium is a metal that tends to lose electrons to achieve a stable electron configuration.
In a chemical reaction, chlorine will typically gain one electron to have the full octet. This is referred to as the octet rule. Since chlorine has seven valence electrons because it is in row 7A, it gains one so it can have 8 electrons.
Ionic bonds are formed when electrons are gained or lost. This is the complete transfer of electrons between the atoms. For e.g sodium(Na) releases its one electron which is transfered to the deserving chlorine atom(Cl). So, chlorine becomes negatively charged and the sodium atom becomes a positive ion(Na+). This is the case when electrons are completely transfered from sodium to chlorine and ionic bond is formed i.e NaCl. Moreover, when electrons are shared between atoms covalent bonds may form.
The increase in oxidation number indicates loss of electrons, while a decrease indicates gain of electrons. For example, if an atom's oxidation number increases from +2 to +4 in a reaction, it has lost two electrons. Conversely, if the oxidation number decreases from +4 to +2, it has gained two electrons.
Chlorine gain an electron in chemical reactions.
Gaining electrons lead to decrease in oxidation state.

The chlorine atom has 7 electrons in its outermost electron shell. This makes it easier for chlorine to gain one electron to achieve a stable octet configuration, forming a chloride ion.
Atoms that gain extra electrons become negatively charged. A neutral chlorine atom.
What man, it's very simple -- since chlorine has atomic number 17 and has 7 electrons in its outermost orbit and being a electronegative element it will most probably gain a electron. Well in which standard are you?
There is zero NET loss or gain of electrons

Nitrogen must gain three electrons.
