Explicación
An ion is an atom or molecule that has a net electrical charge due to the loss or gain of one or more electrons. A negatively charged ion, also known as an anion, is formed when an atom or molecule gains electrons. In the given options, we need to identify the particle that has more electrons than protons, which would result in a negative charge.A. Sodium (Na) with 11 protons, 12 neutrons, and 10 electrons: Sodium has 11 protons and 10 electrons, which means it has one more proton than electrons, giving it a positive charge. Therefore, it is a cation, not an anion.B. Magnesium (Mg) with 12 protons, 12 neutrons, and 12 electrons: Magnesium has 12 protons and 12 electrons, which means it has an equal number of protons and electrons, giving it a neutral charge. Therefore, it is neither a cation nor an anion.C. Hydrogen (H) with 1 proton, 0 neutrons, and 1 electron: Hydrogen has 1 proton and 1 electron, which means it has an equal number of protons and electrons, giving it a neutral charge. Therefore, it is neither a cation nor an anion.D. Chlorine (Cl) with 17 protons, 18 neutrons, and 18 electrons: Chlorine has 17 protons and 18 electrons, which means it has one more electron than protons, giving it a negative charge. Therefore, it is an anion.Based on the above analysis, the correct answer is option D, Chlorine (Cl) with 17 protons, 18 neutrons, and 18 electrons, as it is the only particle among the given options that is a negatively charged ion.
