Look at all of the different substances melting points and find the average
The melting point is greater.
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.
Group 3
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
Manganese: 1 246 0C Technetium: 2 157 0C Rhenium: 3 187 0C
The melting point is greater.
It varies. Boron and thallium both have relatively high melting points while gallium and indium have very low melting points.
No. Group 1 metals (commonly called the alkali metals) have low melting points.
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.
Group 3
Silvery solids with low densities and low melting points are alkali metals. These are located in group one on the periodic table.
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.
The metallic bonds of the alkali metals are are weak.
