Solution

Sure, let's analyze each statement one by one using the periodic table:

  1. Lithium atoms have 3 protons:

    • Lithium (Li) is the third element on the periodic table.
    • The atomic number of lithium is 3, which means it has 3 protons.
    • This statement is true.

  2. Neon atoms have 7 protons:

    • Neon (Ne) is the tenth element on the periodic table.
    • The atomic number of neon is 10, which means it has 10 protons.
    • This statement is false.

  3. Sulfur atoms have 16 protons:

    • Sulfur (S) is the sixteenth element on the periodic table.
    • The atomic number of sulfur is 16, which means it has 16 protons.
    • This statement is true.

  4. Calcium atoms have 20 protons:

    • Calcium (Ca) is the twentieth element on the periodic table.
    • The atomic number of calcium is 20, which means it has 20 protons.
    • This statement is true.

So, the true statements are:

  • Lithium atoms have 3 protons.
  • Sulfur atoms have 16 protons.
  • Calcium atoms have 20 protons.
