Relativity explains why mercury is liquid at room temperature
Original: Relativity behind mercury's liquidity
Chemistry World reports that relativity, not just atomic structure, explains why mercury is liquid at room temperature while other metals are solid. The strong positive charge of mercury's nucleus makes its inner electrons move at relativistic speeds, altering the outer electron behaviour and weakening metallic bonding so the element melts at minus 39 degrees Celsius. The item is drawing attention as an accessible explainer of an often-overlooked link between physics and chemistry.
Why now: A popular science explainer has highlighted the surprising relativistic explanation for mercury's liquid state.
