Based on the naming rules for ions, which of the following is a negatively charged ion (not a polyatomic ion)?(1 point)
chlorine
chlorate
chloride
chlorite
chloride
To determine which of the following is a negatively charged ion (not a polyatomic ion), we can analyze the endings of each term according to the naming rules for ions.
1. Chlorine: Chlorine is the name of the element, and as an element, it usually forms an ion by gaining an electron to achieve a stable electron configuration. Therefore, it can become a negatively charged ion, identified by the suffix "-ide."
2. Chlorate: Chlorate is a polyatomic ion, not a simple ion, since it consists of more than one atom. It has a negative charge and is denoted by the suffix "-ate."
3. Chloride: Chloride is a simple ion and is the negatively charged form of chlorine. It adheres to the naming rule with the suffix "-ide."
4. Chlorite: Similarly to "chlorate," chlorite is another polyatomic ion with a negative charge, indicated by the "-ite" suffix.
Therefore, the correct answer is "chloride," which is a negatively charged ion and not a polyatomic ion.
