The Correct Answer and Explanation is :<\/mark><\/strong><\/p>\n\n\n\n The correct answer is:<\/p>\n\n\n\n A. It gained an electron.<\/strong><\/p>\n\n\n\n Chloride ions (Cl\u207b) are negatively charged ions formed from chlorine atoms. To understand why chloride ions have a negative charge, it\u2019s important to examine the basic concepts of atomic structure and ion formation.<\/p>\n\n\n\n 1. Atomic Structure and Charge:<\/strong> An atom is composed of three main subatomic particles: protons, neutrons, and electrons. Protons have a positive charge, electrons have a negative charge, and neutrons are neutral. In a neutral atom, the number of protons equals the number of electrons, which balances out the charges and results in no overall charge.<\/p>\n\n\n\n 2. Formation of Ions:<\/strong> When an atom gains or loses electrons, it becomes an ion. If an atom gains electrons, it has more negatively charged electrons than positively charged protons, resulting in a negative charge. Conversely, if an atom loses electrons, it has more protons than electrons, leading to a positive charge.<\/p>\n\n\n\n 3. Chlorine Atom and Ion Formation:<\/strong> Chlorine (Cl) is an element with an atomic number of 17, meaning it has 17 protons and, in its neutral state, 17 electrons. The electronic configuration of chlorine is 2-8-7, where it has seven electrons in its outermost shell (valence shell).<\/p>\n\n\n\n 4. Chlorine’s Tendency to Gain an Electron:<\/strong> Chlorine atoms are highly reactive and have a strong tendency to gain one electron to complete their valence shell, achieving a stable electronic configuration similar to that of noble gases. By gaining an electron, chlorine\u2019s electronic configuration becomes 2-8-8. This extra electron gives the chlorine atom a negative charge because the number of electrons (18) now exceeds the number of protons (17), resulting in a Cl\u207b ion.<\/p>\n\n\n\n 5. Charge of Chloride Ion:<\/strong> Thus, when a chlorine atom gains an electron, it becomes a chloride ion (Cl\u207b), with an overall negative charge of -1 due to the additional electron.<\/p>\n\n\n\n In summary, a chloride ion has a negative charge because it has gained an electron, which adds an extra negative charge to the atom. This gain of an electron is crucial for chlorine to achieve a stable electron configuration.<\/p>\n","protected":false},"excerpt":{"rendered":" For which of the following reasons does a chloride ion have a negative charge?
