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.

Melting points of alkali metals?
Alkali metals have relatively low melting points compared to the other metals. Their exact melting points depend on the element itself. But it would be useful to note that their melting points decreases down group I.
Do the molecules of alkanes have strong intermolecular forces and high melting points?
No, alkanes are non polar compounds and have low intermolecular attraction and low melting points.
Do actinides have high or low melting points?
higher M.P
Silvery solids with low densities and low melting points found in group 1?
Silvery solids with low densities and low melting points are alkali metals. These are located in group one on the periodic table.
Why nonmetallic elements have low melting points?
Weak Van Der Waals Forces
Which of these reasons explains why nonmetallic elements have low melting points?
weak van der waals.....
Which of these is NOT a characteristic of an ionic compound A. is a solid B. has a low melting point C. is composed of metallic and nonmetallic elements D. when melted will conduct electricity?
B. it has a high melting point.
Are the elements in the boron group high-melting?
It varies. Boron and thallium both have relatively high melting points while gallium and indium have very low melting points.
Do ionic solids have low melting points?
No, ionic solids have very high melting points. Ionic solids are one of the strongest bonds formed among elements.
Do the halogens have a high or low melting points?
They have low melting points and high reactivity.
Do simple molecular substances have high or low melting and boiling points?
Yes, molecular solids have relatively low melting points.
