What must occur for an atom with one electron to become a cation?

• A. Add 1 neutron
• B. Add 1 proton
• C. Lose 1 electron
• D. Add 2 neutrons

Answer: (C)

For an atom with one electron to become a cation, it must lose one electron. A cation is defined as a positively charged ion, which forms when an atom loses one or more electrons. When the atom loses its single electron, it results in a surplus of protons compared to electrons, thereby creating a positive charge. Having one electron usually corresponds to hydrogen or a similar element. When it loses that electron, it is left with a positively charged ion because the number of protons, which are positively charged, exceeds the number of remaining electrons, which are negatively charged. This process is a fundamental concept in chemistry regarding ion formation and charge neutrality. The other choices involve adding subatomic particles, which would not result in the formation of a cation. Adding neutrons would change the isotope but not the charge, and adding protons would increase the atomic number leading to a different element, not a simple cation formation.
