There are 6 elements of the group 2 elements and all of them have relatively similar melting points. All of these 6 elements are solids and have quite a high melting point but the average from all 6 of them is around 900 degrees Celsius. At around this temperature, most of the elements will start to melt.

∙ 12y agoThere are 3 basic states of matter. These are solid, liquid and gas. The melting point is the temperature at which matter changes completely from solid to liquid, thereby melting. The boiling point is the point at which matter changes completely from liquid to gas, thereby evaporating. It isn't called evaporating point because many liquids partially evaporate long before reaching their boiling point. For water, the melting point is 0 degrees centigrade, and the boiling point is 100 degrees centigrade.

Physical properties of s-block elements?
S-block elements are silvery white, lustrous, highly malleable, having low density, low boiling and melting points, good conductors of heat and electricity . They are highly reactive metals and their reactivity increases down the group.
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 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
Do all metals have high melting points?
Very high. For example, sodium (Na) has a boiling point of 883 degrees C, and iron has a boiling point of 2750.0 degrees C, and gold has a boiling point of 2600 degrees C. You can probably find a Period Table that includes the boiling points of all the elements and much more information.
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.
Explain whyIn Group 17 HF has abnormally high melting and boiling points as compared to other hydrides of the group?
Hydrogen bonding.
How melting and boiling point varied in a period?
Generally melting point and boiling point increase up to group 6 and then decrease.
Why boiling point of noble gases increase down in the group?
The melting and boiling points increase down the group because of thevan der Waals forces. The size of the molecules increases down the group. This increase in size means an increase in the strength of the van der Waals forces.

S-block elements are silvery white, lustrous, highly malleable, having low density, low boiling and melting points, good conductors of heat and electricity . They are highly reactive metals and their reactivity increases down the group.
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 H.E.?
HE is a nother writin form of helium.Its a colorless, odorless, tasteless, non-toxic, inert monatomic chemical element that heads the noble gas group in the Periodic Table and whose atomic number is 2. Its boiling and melting points are the lowest among the elements and it exists only as a gas except in extreme conditions.
What is the trend in melting points as you go down the group of halogens?
The melting point is greater.
How do the boiling points of the noble gases change as you go down?
The boiling points of noble gases increases down a group.
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
Do group one metals have a high melting point?
No. Group 1 metals (commonly called the alkali metals) have low melting points.
Do all metals have high melting points?
Very high. For example, sodium (Na) has a boiling point of 883 degrees C, and iron has a boiling point of 2750.0 degrees C, and gold has a boiling point of 2600 degrees C. You can probably find a Period Table that includes the boiling points of all the elements and much more information.
