An anion always
A) has a positive charge. <\/p>\n\n\n\n

B) contains a group of two or more atoms with a positive charge.
C) contains a metal and a nonmetal. <\/p>\n\n\n\n

D ) forma covalent bonds.
E) has a negative charge<\/p>\n\n\n\n

The correct answer and explanation is :<\/strong><\/mark><\/p>\n\n\n\n

The correct answer is E) has a negative charge<\/strong>.<\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

An anion<\/strong> is a negatively charged ion. This charge arises because an anion gains one or more electrons, which gives it an excess of negative charge. Here’s a breakdown of why option E is correct and why the other options are not:<\/p>\n\n\n\n

    \n
  1. Option A: “has a positive charge”<\/strong><\/li>\n<\/ol>\n\n\n\n
      \n
    • This is incorrect. Anions are specifically negatively charged ions. Ions with a positive charge are called cations<\/strong>, not anions. Cations are formed when an atom loses electrons.<\/li>\n<\/ul>\n\n\n\n
        \n
      1. Option B: “contains a group of two or more atoms with a positive charge”<\/strong><\/li>\n<\/ol>\n\n\n\n
          \n
        • This is also incorrect. While some anions consist of multiple atoms (called polyatomic anions), the charge of the anion is negative, not positive. For example, the sulfate ion (SO\u2084\u00b2\u207b) is a polyatomic anion, and it carries a negative charge.<\/li>\n<\/ul>\n\n\n\n
            \n
          1. Option C: “contains a metal and a nonmetal”<\/strong><\/li>\n<\/ol>\n\n\n\n
              \n
            • This option is partially misleading. An anion does not have to contain both a metal and a nonmetal. While anions can result from the combination of a metal and a nonmetal in ionic compounds (such as chloride, Cl\u207b, which comes from the nonmetal chlorine), the key characteristic of an anion is its negative charge, not the presence of specific types of elements. For example, the oxide ion (O\u00b2\u207b) is formed from a single nonmetal atom, oxygen.<\/li>\n<\/ul>\n\n\n\n
                \n
              1. Option D: “forms covalent bonds”<\/strong><\/li>\n<\/ol>\n\n\n\n
                  \n
                • Anions can indeed form covalent bonds, but this is not a defining characteristic. Covalent bonding involves the sharing of electrons, which can occur between atoms that form anions. However, the key defining feature of an anion is its negative charge<\/strong>, not its bonding type. For example, the hydroxide ion (OH\u207b) can form covalent bonds in water (H\u2082O).<\/li>\n<\/ul>\n\n\n\n
                    \n
                  1. Option E: “has a negative charge”<\/strong><\/li>\n<\/ol>\n\n\n\n
                      \n
                    • This is the correct answer. By definition, an anion<\/strong> is an ion with a negative charge<\/strong>. Anions are formed when an atom or a group of atoms gains one or more electrons, thereby increasing its electron count relative to the number of protons in the nucleus. For example, the chloride ion (Cl\u207b) is formed when a chlorine atom gains an electron.<\/li>\n<\/ul>\n\n\n\n

                      In summary, the defining feature of an anion is that it has a negative charge<\/strong>. This occurs due to the gain of electrons, and it is a fundamental concept in chemistry when dealing with ions and their interactions in chemical reactions.<\/p>\n","protected":false},"excerpt":{"rendered":"
