• 🫗 Liquid oxygen is more magnetic than gas oxygen because the molecules are closer together in liquid form.

Questions & Answers

Q: What is the speaker’s favorite and least favorite element?

Sodium is probably the speaker’s favorite because “Na” was his mother’s nickname and what his children called their grandmother, giving the element a warm personal association. He does not have a definite least favorite, though he is not very fond of elements without proper names, such as those from element 113 onward.

Q: What does the speaker consider the most dangerous element?

He suggests cesium because it reacts so explosively, or fluorine because it attacks nearly all other elements. However, he says potassium frightens him most because a colleague describes it as evil.

Q: How did the Periodic Table of Videos begin?

The speaker met Brady when Brady was making science videos in Nottingham and came to film him. Brady proposed making videos about the periodic table, although the speaker initially doubted that they could say enough about some elements.

Q: What makes Periodic Table of Videos fun for its contributors?

Many different people contribute without knowing what the others are saying or doing. The finished YouTube release is therefore the first time the speaker and the other contributors see everyone’s segments.

Q: Does the speaker have a dog?

No, he has dog toys but no dog. His family once had a small, intelligent Border Terrier, and he now sometimes buys dog toys while visiting the pet shop for food for his son’s pet toad.

Q: Why is liquid oxygen more magnetic than oxygen gas?

Oxygen is magnetic in its gas, liquid, and solid forms. Liquid oxygen produces a much stronger magnetic effect because its molecules are much closer together, placing more molecules inside the flask or test tube than in the gas state.

Q: Why was the Hindenburg omitted from the hydrogen video?

The speaker says it is uncertain whether hydrogen initially caught fire or whether the airship’s painted skin started burning first. Because hydrogen may not have caused the initial explosion, he considers the Challenger space shuttle a clearer example of a hydrogen explosion.

Q: When did the speaker start collecting water bottles?

He started the water bottle collection in 2001 after attending a conference in China. He initially wanted only a few bottles for a photograph, but the collection grew over the years.

Summary & Key Takeaways

• The speaker's favorite element is sodium because of a personal connection, and they don't have a least favorite element.

• The Periodic Table of Videos was started when the speaker met Brady, who wanted to make a video about the periodic table. They didn't believe enough could be said about each element at first.

• The speaker doesn't talk about the Hindenburg in their hydrogen video because it is unclear if hydrogen was the main cause of the explosion.

• The speaker started their water bottle collection in 2001 and it has grown over the years.
