GENERAL KNOWLEDGE

Detailed explanation-1: -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.

Detailed explanation-2: -If we remove an electron from a stable atom, the atom becomes electrically incomplete/unbalanced. That is, there are more protons in the nucleus (positive charges) than there are electrons (negative charges). With an electron removed, the atom possesses a plus one charge, therefore it is a positive ion.

Detailed explanation-3: -Atoms that gain extra electrons become negatively charged. A neutral chlorine atom, for example, contains 17 protons and 17 electrons. By adding one more electron we get a negatively charged Cl-ion with a net charge of-1.

Detailed explanation-4: -If an atom gains electrons, it’s overall charge becomes negative. If an atom loses electrons, it’s overall charge becomes positive. If an atom gains/loses electrons, its mass will not change.

Detailed explanation-5: -Definition: An ion is an atom or molecule which has lost or gained one or more electrons, and carries a net electric charge. If the result is an atom with more electrons than protons, the ion is negatively charged. If there are fewer electrons than protons the ion is positively charged.
