Bromine: -7.2 °C
Selenium: 220.8 °C
Krypton: -157.4 °C
So of the elements listed Kryption has the lowest melting point.
NO. Krypton is one of the inert gases. It has a melting point of 115.79 K, -157.36 °C
Krypton melts at -251.25 °F and boils at -244.12 °F
−156.6°C
The melting point of bromine is -7.2°C, and the boiling point is 58.8°C.
The melting point of a metallic element can vary widely depending on the specific element. For example, the melting point of iron is 1538 degrees Celsius, while the melting point of mercury is -38 degrees Celsius.
The element, Selenium, is a solid at room temperature.
Bromine is the nonmetal element that exists as a liquid under normal conditions. It has a melting point of -7.2 degrees Celsius and a boiling point of 58.8 degrees Celsius.
To determine why chlorine's melting point (-100.98) is higher than krypton's melting point (-157.2), you must look at the electron configuration of the elements. 36Kr: [Ar]4s23d104p6, and 17Cl: [Ne]3s23p5. There is a trend in the periodic table that states that elements with paired electrons in the electron orbitals will have extremely low melting points (why all noble-gases have low melting points). So since krypton is a noble-gas, it has every electron orbital filled, forming an octet, therefore having a lower melting point. Chlorine, has a 3p5 orbital and therefore not completing the octet, or paired p-orbital, therefore having a higher melting point.
NO. Krypton is one of the inert gases. It has a melting point of 115.79 K, -157.36 °C
The melting point of bromine is -7,2 0C. The melting point of chlorine is -101,5 0C.
Selenium has a melting point (of gray selenium) 217°C and boiling point (gray) 684.9°C.
Krypton melts at -251.25 °F and boils at -244.12 °F
-268.93 Celsius
Boiling point 58.78°C Melting point 7.2°C
−156.6°C
Bromine is a nonmetal. It is a member of the halogen group on the periodic table and has properties typical of nonmetals, such as being a poor conductor of electricity and having low melting and boiling points.
The melting point of bromine is -7.2°C, and the boiling point is 58.8°C.
