Detailed explanation-1: -Whenever there is a gain of electrons the element will acquire a negative charge also known as an anion while when an atom loses an electron, the element acquires a positive charge which is also known as a cation.
Detailed explanation-2: -Atoms that lose electrons acquire a positive charge as a result because they are left with fewer negatively charged electrons to balance the positive charges of the protons in the nucleus. Positively charged ions are called cations.
Detailed explanation-3: -If an atom loses or gains electrons, it will become a positively or negatively charged particle, called an ion. The loss of one or more electrons results in more protons than electrons and an overall positively charged ion, called a cation.
Detailed explanation-4: -So if it loses an electron, it contains one proton in excess w.r.t the electrons. Hence if an atom loses an electron, it acquires a net positive charge.
