Positive ions, or cations, have more protons than electrons, resulting in a net positive charge due to the loss of one or more electrons by the atom Positive ions, also known as cations , have more protons than electrons. This imbalance results in a net positive charge. We can understand this by considering that protons carry a positive charge, while electrons carry a negative charge. If an atom loses one or more electrons, the remaining positively charged protons outnumber the negatively charged electrons, leading to a positive charge overall.
For example, a sodium atom (Na) normally has 11 protons and 11 electrons, making it neutral. If it loses an electron, it becomes a Na+ ion with 11 protons and only 10 electrons, which means it has one more proton than electron, giving it a positive charge. In conclusion, positive ions are formed by atoms losing electrons and having more protons than electrons resulting in a net positive charge.
