The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

To answer your question about the chlorine atom:<\/p>\n\n\n\n

1. How many protons does a normal chlorine atom have?<\/strong><\/h3>\n\n\n\n

The atomic number<\/strong> of chlorine is 17<\/strong>. The atomic number of an element tells you how many protons are in its nucleus. Therefore, a normal chlorine atom<\/strong> has 17 protons<\/strong>.<\/p>\n\n\n\n

2. How many neutrons does a normal chlorine atom have?<\/strong><\/h3>\n\n\n\n

The mass number<\/strong> of chlorine is 35<\/strong>. The mass number represents the total number of protons and neutrons in the nucleus. Since we know the atom has 17 protons<\/strong>, we can subtract that from the mass number to find the number of neutrons.<\/p>\n\n\n\n

Number of neutrons = Mass number – Atomic number<\/strong><\/p>\n\n\n\n

Number of neutrons = 35 – 17 = 18<\/strong><\/p>\n\n\n\n

So, a normal chlorine atom has 18 neutrons<\/strong>.<\/p>\n\n\n\n

3. How many electrons does a normal chlorine atom have?<\/strong><\/h3>\n\n\n\n

In a neutral<\/strong> atom, the number of electrons equals the number of protons. Since chlorine has 17 protons<\/strong>, it will also have 17 electrons<\/strong> in its neutral form.<\/p>\n\n\n\n

4. If the chlorine atom had a single negative charge (Cl\u207b ion), how many protons, neutrons, and electrons would the atom have?<\/strong><\/h3>\n\n\n\n

When a chlorine atom becomes a Cl\u207b ion<\/strong> (which has a single negative charge), it gains one extra electron<\/strong> to balance the negative charge.<\/p>\n\n\n\n

    \n
  • The protons<\/strong> remain unchanged because they define the element, so it still has 17 protons<\/strong>.<\/li>\n\n\n\n
  • The neutrons<\/strong> remain unchanged because they are not affected by the charge, so it still has 18 neutrons<\/strong>.<\/li>\n\n\n\n
  • The electrons<\/strong> increase by one, so a Cl\u207b ion<\/strong> will have 18 electrons<\/strong> (17 electrons + 1 extra electron).<\/li>\n<\/ul>\n\n\n\n

    Summary:<\/h3>\n\n\n\n
      \n
    • Normal chlorine atom<\/strong>: 17 protons, 18 neutrons, 17 electrons.<\/li>\n\n\n\n
    • Chlorine ion (Cl\u207b)<\/strong>: 17 protons, 18 neutrons, 18 electrons.<\/li>\n<\/ul>\n\n\n\n

      This is because the charge of the atom affects only the number of electrons, not protons or neutrons.<\/p>\n\n\n\n
