Question

25. Which of the following statements is true for

Answer 1

Answer:

Sulfur's atomic number is 16, meaning it has 16 protons and 16 electrons. This also rules out the statement "it has 17 neutrons". This also rules out the second statement "it has more electrons than argon". Argon's atomic number is 18, telling us it has 18 electrons and 18 protons. Of course, 16 is less than 18, so argon has more. Sulfur's atomic symbol is S, not Su, which doesn't even represent an element at all. This leaves us with the last statement "it has 6 electrons on its third energy level." This is true, as Sulfur does indeed have 6 electrons filling its third energy level.
