Which element has a higher melting point potassium or calcium?
Calcium at 860 degrees celsius potassium melts at a mere 65 degrees celsius
Why Does Chlorine or Silicon have a higher melting point?
Chlorine has a higher melting point than silicon because chlorine molecules are held together by stronger covalent bonds compared to the silicon atoms in silicon. This makes it harder to break the bonds in chlorine, requiring higher temperatures to melt. Silicon has weaker metallic bonds which results in a lower melting point.
In the reaction of calcium with chlorine which atom is oxidized?
calcium + chlorine yields calcium chloride oxidation means loss of electrons, it's the calcium atom the oxidizes into the calcium cation +2. the chlorine is being reduced from chlorine neutral to chloride -1 anion.
What is the nature of the CaCl bond in a molecule of calcium chloride CaCl2 if the electronegativity value of calcium is 1.0 and that of chlorine is 3.16?
The bond between calcium and chlorine in calcium chloride (CaCl2) is considered ionic. This is because of the large electronegativity difference between calcium (1.0) and chlorine (3.16). The higher electronegativity of chlorine attracts the electron pair in the bond closer to itself, resulting in the formation of an ionic bond where chlorine gains electrons from calcium.
Why does sulfur have a higher melting point than chlorine?
Sulfur has a higher melting point than chlorine because sulfur atoms are held together by stronger covalent bonds compared to chlorine atoms, which are held by weaker van der Waals forces. The stronger bonds in sulfur require more energy to break, resulting in a higher melting point.
Why calcium fluoride has a higher melting point than chlorine fluoride?
Calcium fluoride has a higher melting point than chlorine fluoride because the calcium ion has a higher charge density than the chlorine ion, leading to stronger electrostatic forces of attraction between the calcium and fluoride ions in the lattice structure. This results in a greater amount of energy required to break these bonds, leading to a higher melting point for calcium fluoride compared to chlorine fluoride.
Why is melting point of sodium fluoride higher than that of sidium iodide?
The higher melting point of sodium fluoride compared to sodium iodide is due to stronger forces of attraction between the ions in the crystal lattice of the fluoride compound. Fluoride ions are smaller and have a higher charge density compared to iodide ions, leading to stronger electrostatic forces between the ions in sodium fluoride, resulting in a higher melting point.
Is the melting point of bromine higher or lower than the melting point of chlorine?
The melting point of bromine is -7,2 0C. The melting point of chlorine is -101,5 0C.
Does Chlorine or Silicon have a higher melting point?
Siliocone has a higher one. Chlorine is already a gas at room temperature.

Why does calcium oxide have a higher melting point than sodium chloride?
Calcium oxide has a higher melting point than sodium chloride because calcium oxide has stronger ionic bonds due to the higher charge of calcium ions (+2) compared to sodium ions (+1). The stronger ionic bonds in calcium oxide require more energy to break, resulting in a higher melting point.
Why does sodium fluoride have a higher melting point than lithium fluoride?
Sodium fluoride has a higher melting point than lithium fluoride because sodium ions are larger and have more electrons than lithium ions, resulting in stronger electrostatic forces between ions in the sodium fluoride lattice. This makes it harder to break the ionic bonds in sodium fluoride, requiring more energy to melt it compared to lithium fluoride.

What is the melting point for the element chlorine?
Chlorine melts at -101.5 °C Chlorine boils at -34.04 °C Because normal temperature is so much higher than this, Chlorine is normally a gas.
Is it easier to take electrons away from chlorine or from calcium?
It is easier to take electrons away from chlorine because it is in Group 17 of the periodic table with a higher electronegativity value compared to calcium in Group 2. Chlorine has a greater tendency to gain electrons to achieve a stable electron configuration.
