Answer: In the reaction, magnesium atoms lose electrons.
Explanation:
An ionic compound is defined as the compound which is formed when electron gets transferred from one atom to another atom. These are usually formed when a metal reacts with a non-metal or a metal reacts with a polyatomic ion or a reaction between two polyatomic ions takes place.
Magnesium is 12th element of the periodic table having electronic configuration of [tex]1s^22s^22p^63s^2[/tex]
This element will loose 2 electrons to form [tex]Mg^{2+}[/tex] ion
Chlorine is 17th element of the periodic table having electronic configuration of [tex]1s^22s^22p^63s^23p^5[/tex]
This element will gain 1 electron to form [tex]Cl^-[/tex] ion
By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.
The ionic compound formed is [tex]MgCl_2[/tex]
Hence, in the reaction, magnesium atoms lose electrons.
The branch of science which deals with chemicals and bonds is called chemistry.
The correct answer is A.
Those elements which are extra electrons and ready to donate to other is called metals.
The metals have extra electrons due to which they remain unstable. They lose or donate the electron to the nonmetal which is electron-deficient and become the stable compound.
Metal becomes a cation after losing electrons.
Hence the correct option is A that loses electrons.
