Mercury has a unique electron configuration which strongly resists removal of an electron, making it behave similarly to noble gas elements. As a result, mercury forms weak bonds and is a liquid at room temperature.

[@insane_troll]

It is also a relativistic effect. The outermost orbital 6s is not only filled (similar to noble gases, except they have filled s and p orbitals), but the electron is moving more than half the speed of light. This means that the effective mass is significantly larger than the rest mass, and because the orbital radius is inversely proportional to the mass the electron has to be closer to the nucleus. This effect reduces the melting point by about 100K.

Whenever Neil says "I don't know, but I'm going to give an answer that probably won't be satisfying," you know he's going to give you a veeeeery long, veeeeery satisfying response.

[@raukoring]

I don't understand where are they coming from, but there's A LOT of people on internet hating Neil and saying he's fake and so on. I don't get what could be their agenda. It's absolutely clear that guy is extremely educated. Maybe they're not getting his personality that he's just so crazy into science and educating that he often can't control himself and jumps into others speech.. but most of the times it's just cute and not really rude.

[@emleecee]

This is such a beautiful sentiment! Beautiful and so, so true.

[@Raz.C]

The low melting point of elemental Mercury is due primarily to the nature of its electron orbitals. If I recall correctly, Mercury has a filled 6s orbital and a filled 5s, 5p, 5d and 4f orbital. So it has filled 4 and 5 level orbitals with a filled 6s orbital, lending to its +1 and +2 oxidation states which also makes it hold on to the 6s2 electrons reasonably tightly. In many ways, Mercury resembles the electron configuration of the noble gasses and mimics the behaviour of noble gasses too. Because of this, the bonds that Mercury forms with other elements are relatively weak, in the same way that Radon can form weak bonds (Radon electron configuration same as mercury but with 6p6 orbital). In point of fact, the "Island Of Stability" centres around Copernicium, which is directly beneath Mercury on the periodic table and as Neil mentioned, elements share MANY similarities with those above and below it on the periodic table. Anyway, all these factors contribute to Mercury being very stable and thus having a low melting point.

I've seen that experiment done, but don't remember if Gallium was the one. NaK is an alloy of Sodium and Potassium that is liquid at room temperature, but that alloy is looking so hard to react with something that it will even grab water vapor and Oxygen from the air and potentially ignite. @ 39:12 There was so much scientific work done on the Deep Field photo, and we learned so much from it.

When answering the question of why mercury is liquid at "room temp" Neil mentions another metal, whose name he can't remember, and which also has a low freezing point. Might the one he's looking for be gallium? It's solid at room temperature, but melts at just a little bit warmer, say the temperature of a freshly brewed cup of tea. A book I read about the periodic table takes you through every element on it and explains unusual or unique things about them, and describes a practical joke of putting a spoon made of gallium into a hot cup of tea, in which it melts, ideally while the intended drinker of said cup is waiting for it to cool sufficiently to be consumed ("where'd my spoon go!?!?"). I don't know what makes gallium's melting point what it is, but could that answer inform why Mercury's is as low as it is? Not sure whether drinking that tea would then be wise...

When Chuck makes Neil laugh 😊

[@captainzappbrannagan]

The greatest thing about Neil is his movie career. The second greatest is he admits when there's something he doesn't know. Why Mercury liquid? Most metal atoms readily share valence electrons with other atoms. The electrons in a mercury atom are bound more tightly than usual to the nucleus. In fact, the s electrons are moving so fast and close to the nucleus that they exhibit relativistic effects, behaving as if they were more massive than slower-moving electrons. It takes very little heat to overcome the weak binding between mercury atoms. Because of the behavior of the valence electrons, mercury has a low melting point

[@TJ-ed8mw]

[@sportsfan220]

[@GlassDeviant]

If you google "why is Mercury a liquid at room temperature?", everyone stumbles through trying to answer that question. The only logical conclusion is that nobody actually knows the root reason. Yes, its melting point is -40C, but that doesn't really explain why because you are left with another question, namely "why is the melting point of Mercury -40C?"

[@MrT------5743]

Why is the melting point of water 0C? Sometimes there is not a reason why something is, it just is. Like Neil says all the time: "The universe is under no obligation to make sense to you."

[@heresthethingyouguys]

Every "Why" question is pointless no matter the topic. Science has no answer to why questions.

[@oldcowbb]

@@heresthethingyouguys why doesn't always mean it is question about purpose, fyi, it can be a question about causes

[@GoldSrc_]

@@oldcowbb In that case, explaining the "how" something works would be better than "why". But I assume that "why" is often used by people who need to know the "how", but use instead "why". In the end, the question of "why" in science doesn't make as much sense or is as useful as knowing the "how".

[@seafodder6129]

It's actually going to Lagrange Point 2, which is waaaaaay past the moon altogether. So it's technically not even going to be orbiting Earth, it'll be orbiting the sun. When Neil mentioned putting things on the far side of the moon (there is no "dark side" of the moon) he was referring to radio telescopes so the mass of the moon would block out all the radio noise being broadcast by us here on Earth.

[@11892rosa]

Sadly, he was referring to only the possibility of a radio telescope where the perfect place to put it would be the dark side of the moon. That would've been cool though
