What is the trend in melting points as you go down the group of halogens?
The melting point is greater.
How would you find the relative melting points of a group of substance?
Look at all of the different substances melting points and find the average
What is the melting point for Mg?
The melting point of magnesium is 650 degrees celcius. It has the lowest melting point among all the group II metals (alkaline earth metals), though the melting points generally decrease down the group - magnesium is an exception and has the lowest melting point among them.
Which atomic groups tend to go from higher to lower melting points reading from top to bottom?
Group 3
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

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 group one metals have a high melting point?
No. Group 1 metals (commonly called the alkali metals) have low melting points.
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.
Which atomic group tend to go from higher to lower melting points reading from top to bottom?
Group 3
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.
What is the melting point for Mg?
The melting point of magnesium is 650 degrees celcius. It has the lowest melting point among all the group II metals (alkaline earth metals), though the melting points generally decrease down the group - magnesium is an exception and has the lowest melting point among them.
Why do melting points of group 1 become lower?
The metallic bonds of the alkali metals are are weak.
Do nonmetals have higher melting points or lower boiling points?
lower melting points
Explain whyIn Group 17 HF has abnormally high melting and boiling points as compared to other hydrides of the group?
Hydrogen bonding.
Which ions have high melting points?
positive ions have high melting points
