Why Does Chlorine or Silicon have a higher melting point?
the further one moves down the periods, the melting point decreases. since sillicon is placed before chlorine, chlorine has lower melting point.
Which element has a higher melting point potassium or calcium?
Calcium at 860 degrees celsius potassium melts at a mere 65 degrees celsius
Why the melting point of potassium fluoride is higher than the melting point of potassium iodide?
KF has small size than KCl. So the packing of atoms / ions in KF is more than that in KCl. So a larger energy is needed to separate the atoms from solid state to liquid state and hence KF has higher melting point than KCl.
Why does sulfur have a higher melting point than chlorine?
volatility increase across a period and so chlorine is more volatile and therefore is more of a gas than sulphur and so it needs more energy to melt
Why does chlorine have a higher boiling point than krypton?
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.
Why calcium fluoride has a higher melting point than chlorine fluoride?
Calcium fluororide is ionic whereas chlorine fluoride is covalent.
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 Chlorine or Silicon have a higher melting point?
the further one moves down the periods, the melting point decreases. since sillicon is placed before chlorine, chlorine has lower melting point.
Why is melting point of astatine higher than chlorine?
Because astatine is a heavier halogen.
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.
Does salt have a higher or lower melting point than Na or Cl?
Common table salt (sodium chloride) has a much higher melting point than either sodium or chlorine.
Why does sodium fluoride have a higher melting point than lithium fluoride?
Because the atomic weight of sodium is greater than the atomic weight of lithium; sodium is under lithium in the column of alkali metals.
Which element has a higher melting point potassium or calcium?
Calcium at 860 degrees celsius potassium melts at a mere 65 degrees celsius
What has a larger atomic radius Cl ion or Ca ion?
Calcium has the larger atomic radius than chlorine. Calcium has four energy levels, whereas chlorine has three energy levels. The higher the energy level, the farther it is from the atomic nucleus.
Will shocking with chlorine make PH go up?
yes, and the pH can go up significantly depending on what type of chlorine used for shocking. Liquid chlorine (sodium hypochlorite) will cause the PH to increase at a higher rate than that of granular chlorine (such as calcium hypochlorite)
Why the melting point of potassium fluoride is higher than the melting point of potassium iodide?
KF has small size than KCl. So the packing of atoms / ions in KF is more than that in KCl. So a larger energy is needed to separate the atoms from solid state to liquid state and hence KF has higher melting point than KCl.
