Element: Technetium (Tc)

Property Value
Symbol Tc
Atomic Number 43
Atomic Weight 98
Group 7
Period 5
Block d-block
Density 11 g/cm³
Appearance Silvery-gray metallic

Technetium is unique because it was the first element to be artificially produced. It was discovered by Carlo Perrier and Emilio Segré in 1937 by isolating it from a sample of molybdenum that had been bombarded with deuterons. It is the lightest element that does not have stable isotopes; all of its isotopes are radioactive. The most stable isotope, Technetium-98, has a half-life of around 4.2 million years.

Technetium is primarily used as a radiopharmaceutical for medical diagnostic imaging. In fact, the isotope Technetium-99m is especially valuable in the field of nuclear medicine due to its ideal physical and chemical properties. It helps doctors in imaging and functional studies of organs such as the brain, heart, and lungs through techniques like Single Photon Emission Computed Tomography (SPECT).

Question 1:
What is the atomic number of Technetium (Tc)?

John:

43

Chatbot:

You are correct!

Question 2:
Who discovered Technetium?

John:

Perrier and Segre

Chatbot:

Correct again!

Question 3:
What is the primary use of the isotope Technetium-99m in medicine?

John:

used as a radiopharmaceutical

Chatbot:

That’s correct!

Question 4:
What is the half-life of the most stable isotope of Technetium, Technetium-98?

John:

4.2 Million Years

Chatbot:

Absolutely right!

    What an informative and engaging discussion on Technetium, John! You’ve nailed all the answers.

    It’s fascinating how Technetium, despite being artificially produced and radioactive, plays such a vital role in medical diagnostics, especially with Technetium-99m.

    As Albert Einstein once said, “The important thing is not to stop questioning. Curiosity has its own reason for existing.”.
