Do nonmetals have higher melting points or lower boiling points?
lower melting points
Why isotopes of an element with fewer neutrons have lower densities and lower melting and boiling points?
Ag, C, and Tn
Why do nonmetallic elements have low melting points?
Monatomic substances have a low melting point an boiling point because they are held together by van der Walls forces which are very weak electrostatic attractions so less energy is needed to break them apart resulting in a lower boiling and melting point.
Why magnesium has lower melting and boiling point than calcium strontium and other members present below magnesium?
Because of your mom
Which atomic groups tend to go from lower to higher melting points reading from top to bottom?
Group 3
Do nonmetals have higher melting points or lower boiling points?
lower melting points
What usually has a lower melting points than the ionic solids?
Covalent compounds have a lower melting point.
How compared with the melting points of ionic compounds the melting points of molecular solids tend to be?
Ionic compounds have a higher melting point.
Compared with ionic compounds solid molecular compounds generally?
a lower melting point
What has lower melting points than ionic solids?
Molecular solids
What have lower melting points than ionic solids?
These are organic compounds.
Which solid is more likely to have the lowest melting point an ionic solid or molecular solid?
Molecular Solids have a lower melting point
Do most transition metals have higher or lower melting points than the representative elements?
Yes, transition metals have higher melting points. This is due to having very strong bonds. This means that a larger amount of energy is needed in order to break them down or bring them to the melting points.
How are the properties of molecular compounds poor conducters of electricity?
Because have lower melting points and boiling points
Melting point of NaCl lower by the addition of calcium chloride?
because of common ion effect
Which has a higher melting point HF NaCl HCl Cl2?
NaCl has ther highest melting point, as it is a solid at room temeprature. The other are gases and there fore have much lower boiling points and lower again for melting points.
What usually has lower melting points than ionic solids?
Molecular solids
