Which of the following elements both half chemical symbols that are two letters. The first letter is S.

5 answers

The elements that have chemical symbols consisting of two letters with the first letter being "S" are:

  1. Sulfur (Symbol: S)
  2. Samarium (Symbol: Sm)
  3. Scandium (Symbol: Sc)
  4. Selenium (Symbol: Se)

If you need additional information about these elements, feel free to ask!

The answer choices are

Tin and antimony

potassium and tungsten

Sliver and lead

Mercury and iron

Based on the answer choices provided, none of the elements listed have a chemical symbol that starts with the letter "S."

  • Tin (Sn) and Antimony (Sb)
  • Potassium (K) and Tungsten (W)
  • Silver (Ag) and Lead (Pb)
  • Mercury (Hg) and Iron (Fe)

However, if you meant elements that simply have a two-letter symbol and start with "S," from your choices, the one that fits this criteria is:

  • Silver (Ag) — does not start with "S."
  • Lead (Pb) — does not start with "S."
  • Tin (Sn) — does not start with "S."
  • Antimony (Sb) — does not start with "S."
  • Mercury (Hg) — does not start with "S."
  • Iron (Fe) — does not start with "S."

Thus, none of the answer choices actually contain elements that satisfy your original question regarding two-letter chemical symbols starting with "S." The only elements fitting your criteria (S) from the periodic table are:

  • Silicon (Si)
  • Sulfur (S)
  • Samarium (Sm)
  • Scandium (Sc)
  • Selenium (Se)

What’s the answer?

Based on your original question about elements that have two-letter chemical symbols where the first letter is "S," let's evaluate the provided answer choices against that criterion:

  1. Tin and Antimony (Sn, Sb) - No "S" as the first letter.
  2. Potassium and Tungsten (K, W) - No "S" as the first letter.
  3. Silver and Lead (Ag, Pb) - No "S" as the first letter.
  4. Mercury and Iron (Hg, Fe) - No "S" as the first letter.

None of your answer choices include elements with chemical symbols that start with "S."

If we strictly adhere to the criteria, none of the listed pairs fit the requirement. If you were looking for pairs of elements containing one that starts with "S" and complies with the question's conditions, please confirm or clarify, and I can assist you further!
