potassium melting point

Potassium, a soft alkali metal, has a precisely measured melting point of 63.38°C (336.53 K), making it one of the lowest among metallic elements and allowing it to melt in a warm pan or even on a hot day.

This low melting temperature stems from its weak metallic bonding due to a single valence electron, leading to fascinating behaviors like floating on water before reacting violently.

Key Properties

Potassium transitions from solid to liquid at this point, with values consistently reported around 63-64°C across scientific sources, though minor variations arise from measurement precision.

  • Exact value : 63.38°C (336.53 K) per thermochemical data.
  • Approximate in °C : Often rounded to 63.5°C or 64°C in educational contexts.
  • Comparison : Lower than sodium (97.8°C) but higher than cesium (28.5°C), highlighting Group 1 trends.

Practical Implications

In labs, this low melt point requires careful storage under oil to prevent oxidation, as molten potassium ignites easily in air.

Industrially, pure potassium sees limited use due to reactivity, but compounds like potassium formate leverage "melting" properties for de-icing.

No recent news or forum trends discuss breakthroughs here, as it's a well- established fact unchanged since early 20th-century measurements.

Fun Fact

Imagine holding a chunk of potassium on a summer sidewalk—it could literally melt in your hand, though touching it bare is a terrible idea due to its caustic nature! TL;DR : Potassium melts at 63.38°C, soft and reactive like a sci-fi liquid metal.
