How Well Do You Know the Element Called Actinium? PERIODIC TABLE OF ELEMENTS QUIZ (Part 1)

Do you love chemistry? Are you an avid fan of Dmitri Mendeleev, the one who founded and created the Periodic Table of Elements? If you are, then I have something for you, a quiz series which is all about the elements in a periodic table.

We all have known some of them during our school days, so now here’s our chance to know them one by one, starting with my first quiz which is all about actinium.

Take this quiz now and have some learning fun facts too. Make sure you get 6/10 for a passing score.

Good luck and have fun!

  • What is the element symbol for actinium?

    • Ac
    • At
    • An
    • A
  • Which of the following best describes actinium?

    • It is a soft, silvery-white radioactive metal, actinium reacts rapidly with oxygen and moisture in air forming a white coating of actinium oxide that prevents further oxidation.
    • It is a relatively rare element in the universe, usually occurring as a product of the spallation of larger atomic nuclei that have collided with cosmic rays.
    • It is the only metallic element that is liquid at standard conditions for temperature and pressure.
    • It is a soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal.
  • Actinium was first discovered in 1899 by French chemist who also suggested the same name for that element. What was his name?

    • William Ramsay
    • André-Louis Debierne
    • Jules Janssen
    • Nicolas Lémery
  • Which of the following is the atomic number for actinium?

    • 67
    • 102
    • 43
    • 89
  • The name of actinium was derived from the Greek word “aktinos” or “aktis” meaning what?

    • light or luster
    • active or energetic
    • ray or beam
    • extremely hot
  • Actinium was independently discovered again in 1902 by German chemist who had not heard of Debierne’s work. What was his name?

    • Fritz Haber
    • Adolf von Baeyer
    • August Kekule
    • Friedrich Oskar Giesel
  • What was the suggested name for the second discovery of actinium in 1902 by a German chemist where the name was derived from an English word that means “to emit rays”?

    • ranium
    • emanium
    • sunium
    • lightnium
  • Which sample was used by the first discoverer of actinium where he used some of it from which polonium and radium has been already extracted to it, where Marie Curie first discovered them and helped him according to some sources?

    • andradite
    • uraninite
    • aegirine
    • elbaite
  • One of the more noteworthy actinium facts is that the element glows in the dark due to ionization of gases in the air by radiactivity. What color does it glow in the dark?

    • blue
    • white
    • green
    • yellow
  • Which of these following fun facts is not true about actinium?

    • Actinium is about 150 times more radioactive than radium!
    • Actinium presents a health hazard. If ingested, it is deposited into the bones and the liver, where radioactive decay damages cells, potentially leading to bone cancer or other illnesses.
    • Actinium is present at an abundance of 0.0005 parts per trillion by mass in the Earth’s crust. Its abundance in the solar system is negligible overall. There is about 0.15 mg of actinium per ton of pitchblende.
    • All isotopes of actinium are non-radioactive.
