Potassium is K and Krypton is Kr. If symbols, then K would be potassium.
The metal with the highest melting point is Tungsten (W) at 3410 degrees Celsius (6170 degrees Fahrenheit). However, technically Carbon has a higher melting point, though not under normal atmospheric conditions. This is because it sublimates (turns directly from a solid to a gas) at 6740 degrees Fahrenheit under normal circumstances.(Carbon also doesn't count because it is not a metal, but a nonmetal).However, if you are taking consideration of all elements and explore which element has the highest boiling point, then it is Rhenium (Rh), which turns to gaseous form at the temperature of 5592*C (10 097.6*F), followed by Tungsten (W) which boils off at 5540*C (10 004*F).Hope it was useful...!!!

At 101.3 kPa and 298 K, the element present is likely to be oxygen (O2) due to its high natural abundance in the atmosphere and its physical properties at that temperature and pressure.
Tungsten It melts at 3683 K
Lead (Pb) has a melting point of approximately 600 kelvin. If you were looking for an element with a melting point around 300 K, you may have been thinking of mercury (Hg), which has a melting point of around 234 K.
At these conditions, the ideal gas law should give a very good prediction of molar density of a gas. Solving the ideal gas law for molar density you get: n/V = P/RT For the stated conditions this means n/V = (1 bar)/[(8.3144622 x 10-5 m3 bar K−1 mol−1)(300 +273.15)K] = 20.98445 moles/m3 Note that it is impossible to calculate the mass density of the gas unless you specify the composition of the gas.
Zn has the density of 7,31 g/cm3 and Br has the density of 3,119 g/cm3 at 300 K. The heighest density has the metal iridium rho = 22,560 kg/m3 or 22.56 g/cm3 and the metal osmium rho = 22,610 kg/m3 or 22.61 g/cm3.
300 k is three hundred thousand
To convert 300 K to Celsius scale, you simply subtract 273.15 from 300 K. Therefore, 300 K is equivalent to 26.85 degrees Celsius.
After Carbon (in form of diamond), the element Tungsten (W) has the second highest melting point of 3695 K, 3422 °C, 6192 °F
Potassium, with an Atomic Number of 19, is designated by the symbol 'K'.
element K is potassium and yes it is a metal.
The density of fluorine gas at standard conditions (0°C and 1 atm pressure) is 1.696 g/L. It is a very light and highly reactive element.
Potassium' formula is 'K' , from the Latin for 'Kalium'.
