What is a cation?

• A. A negatively charged ion
• B. A positively charged ion
• C. An atom with no charge
• D. A neutral molecule

Answer: (B)

A cation is defined as a positively charged ion. This occurs when an atom or molecule loses one or more electrons, resulting in a net positive charge. The loss of negatively charged electrons leaves the ion with a surplus of positively charged protons, leading to the overall positive charge characteristic of cations. For instance, when sodium (Na) loses an electron, it becomes Na⁺, which is a typical example of a cation. This process is important in various chemical reactions, particularly in ionic bonding and conductivity in solutions. Understanding the nature of cations is essential for comprehending concepts related to chemical reactivity, charge balance in compounds, and the behavior of electrolytes.
