Question

What are the four liquid elements?/

Answer 1

\[Hg, ... , ... , ... . \]

Answer 2

under standard conditions, there are only 2 liquid elements: Hg, and Br. Gallium melts at around 30C, which is enough so that your hand will melt it, but it's not classified as a liquid at room temp.

Answer 3

thats three , and what about Cs cesium

Answer 4

or Fr francium

Answer 5

ops that is 5

Answer 6

technically cesium melts at 28C, which is not RT, so it is also not called a liquid at room temp. francium is so radioactive that no one has managed to obtain a sample of francium large enough for long enough to find out what its MP ought to be. common consensus has only 2 liquid elements at room temp: Hg, and Br

Answer 7

yeah but i never mentioned STP

Answer 8

Why is Mercury a liquid

Answer 9

none of the elements around it are liquid, bromine is between gasses and solids, cesium and francium are in a corner gallium is metaloid,
mercury is just between metals

Answer 10

sure lead and gold have lowish meting temperatures, but no where near as low as Hg, what is the cause

Answer 11

if you don't specify either room temp or STP, then technically all elements can be liquid

Answer 12

To my knowledge, only Hg and Br can be classified as liquid element under standard conditions. But for your interest, you may google 'liquid element'. One of the websites said the the following elements can become liquid at 25~40 degree Celsius:
Francium
Cesium
Gallium
Rubidium

Probably, i would agree with JFraser's saying that technically all element can be liquid...

Answer 13

But why is Mercury a Liquid

Answer 14

Because it has a freezing point = -38.83(at rm temp, it's not cold enough for it to freeze) and boiling point = 356.73 (at rm temp, it is not hot enough for it to be a gas)
Hmm, actually, I don't really know, sorry :(

Answer 15

yeah that is what defines it as a liquid,
not the cause

Answer 16

something to do with that 1 valence electron?

Answer 17

Sorry, but that's beyond my study, which I can't really help you. Once again, google is your best friend.
Perhaps you can read the following site. I don't know if it helps

Answer 18

i will get to the bottom of this and let youse know
