Well, if you look at it in a purely elemental capacity we see trends that with an increase in electron shielding, we get a decrease in melting point.
This is said to be because with larger electron shielding we have a lower Z(eff) (effective nuclear charge) between atoms meaning weaker forces keeping them together and thus a lower melting point.
I think this is an important logical procedure when understanding why things melt and what things like Z(eff) really mean in terms of an atom's behaviour. It's a good learning tool but, outside of periodicity, I would never feel comfortable attributing a melting point to electron shielding. Good idea for elements, terrible idea for molecules.

Are freezing and melting points characteristic properties?
The melting point (or freezing point) is a characteristic for materials.
Are melting and boiling point physical properties of a substance?
Melting and boiling points are physical properties of materials.
Does a liquid freeze or unfreeze at 32 degrees Fahrenheit?
Water does, and there are many that will have similar melting points. However all liquids have slightly different melting points, so it does depend.
Both melting and boiling points of water at sea level?
Melting/Freezing point : 0 oC or 273.15 Kelvin Boiling point: 100 oC or 373.15 Kelvin
Is a heat conductor a material with a high melting point?
A heat conductor is a material that readily transports heat from one location to another through the process of conduction. Some materials with high melting points are actually good insulators and very poor heat conductors, whole some materials with low melting points may be good conductors.
Why is electron shielding not a factor when you examine a trend across a period?
Electron shielding is not a factor across a period because they all have the same number of electron shells! No further (extra) shells means that they are all affected by electron shielding equally.
In going down a group in the periodic table what effect does electron shielding generally have on the effective nuclear charge acting on the outermost electron in an atom?
Electron shielding decreases the effective nuclear charge.
The attraction of the nucleus for the outer electrons in large atoms is lessened as a result of?
Its all called electron shielding.
What is Light weight with high melting point in group 2 of elements?
all group 2 metals are light weight with high melting points beryllium however has the highest melting point due to the low number of electrons shielding the nucleus fro the delocalised atoms
What is the shielding effect trend?
The reduction in the force of attraction between the nucleus and outer most electron is known as shielding effect
Do all of the noble gases have at least 3 electron shielding layers?
No, not all noble gases have at least 3 electron shielding layers. The noble gas helium (He) has only two electron shielding layers, while the remaining noble gases (Neon, Argon, Krypton, Xenon, and Radon) have three or more electron shielding layers.
The addition of electron shells results in?
The addition of electron shells results in more shielding of electrons from the nucleus.
In which orbital does an electron in a phosphorus atom experience the greatest shielding?
1s
How many shielding atoms does magnesium have?
Magnesium has 3 electron shells.
The fewer electron shells the shielding of electrons from the nucleus.?
less
Do nonmetals have higher melting points or lower boiling points?
lower melting points
What does electron shielding most affects?
It had most effect on outer shell electrons.
