SSC MTS EXAM

Detailed explanation-1: -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.

Detailed explanation-2: -A monatomic ion (also called simple ion) is an ion consisting of exactly one atom. If, instead of being monatomic, an ion contains more than one atom, even if these are of the same element, it is called a polyatomic ion.

Detailed explanation-3: -Atoms where the electrons and protons are not equal are called ions. Ions are charged particles. They can be either positively charged ions or negatively charged ions. If an atom is charged electrically it is considered an ion.

Detailed explanation-4: -Any charged atom is called an ion. However, there are many individual charges that can potentially make up an atom. A positive charge is carried by protons, and a negative charge is carried by electrons, and in a neutral atom, there are an equal number of protons and electrons.
