Being a covalent compound, the intermolecular forces between the Cl2O molecules are weak and easily overcome. Therefore little heat energy, in terms of low boiling point is involved.
Chlorine has a low melting point of -100.98°C and a low boiling point of -34.6°C.
Barium oxide has a high melting point of around 1,923 degrees Celsius. This is typical for many metal oxides, as they tend to have high melting points due to the strong ionic bonds between the metal and oxygen atoms.
The melting point of lead is 327oC, as taken from my periodic table.
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.
Phosphorus has a relatively low melting point of 44.1°C (111.4°F). This allows it to melt at relatively low temperatures compared to many other elements.
Chlorine has a low melting point of -100.98°C and a low boiling point of -34.6°C.
Barium oxide has a high melting point of around 1,923 degrees Celsius. This is typical for many metal oxides, as they tend to have high melting points due to the strong ionic bonds between the metal and oxygen atoms.
The melting point of helium is the lowest: -272,20 0C.
Naphthalene has a relatively low melting point of around 80 degrees Celsius.
That depends on the solid: ice has a very low melting point, lard and butter have low melting points, chocolate has a relatively low melting point, wax has an intermediate melting point, lead has a high melting point, iron has a very high melting point, tungsten has an extremely high melting point.
It has a melting point of 113 degrees celieus
low resistivity and low melting point.
The melting point of technetium is 2 157 0C- it is not low.
it has a low melting point
Polonium has a low melting point: 254 0C.
The element in question is chlorine (Cl). Chlorine is a diatomic molecule in its gaseous state, with a low melting point and boiling point. It readily reacts with metals to form ionic compounds, known as salts, due to its strong electronegativity and desire to gain an electron.
Tin has a relatively low melting point, at 231.93oC, or 449.47oF.
