Explanation:
Detailed explanation-1: -If an atom or molecule gains an electron, it becomes negatively charged (an anion), and if it loses an electron, it becomes positively charged (a cation). Energy may be lost or gained in the formation of an ion.
Detailed explanation-2: -An electron is a negatively charged subatomic particle that can be either bound to an atom or free (not bound).
Detailed explanation-3: -Some atoms can attract additional electrons so they become negatively charged. Atoms which are not electrically neutral are called ions. One can collect electric charge by transferring electrons. Materials with an excess of electrons are negatively charged.
