What is Light weight with high melting point in group 2 of elements?
Firebug2011
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 relationship between melting point and atomic number for group seven elements?
As the atomic number increases so does the melting point, meaning the the molecules get stronger therefor you need a higher melting point to break the molecules.
Did mendeleev group the elements by density?
Chemistry books say that he grouped the elements by atomic weight. That is not the same as density.
Melting points and boiling points of Group 1 elements?
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.
What is the trend in melting points as you go down the group of halogens?
The melting point is greater.
Elements of Group 1 Are Called what?
Elements in group 1 are called Alkali Metals, after that group 2 elements are called Alkali Earth Metals, group 3-12 elements are called Transition Elements.
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.

Synthetic elements are found in what group?
The Actinoids group contain all the synthetic elements. All the elements that have an atomic weight of 95 and above do not occur naturally. They are part of the actinoid elemental group.
Does lead have a high or low melting point?
Nitrogen has an extremely low melting point. The element nitrogen solidifies at -210 °C, only 63° above absolute zero. A phase change can be made under very high pressure, and the resultant solid is then stable at normal pressure if kept cold enough. This has the potential for making nitrogen superconducting magnets.
Mendeleev noticed that if he organized the elements by atomic weight certain patterns emerged. For instance elements in the same group (family) appeared to have the same?
These elements have similar chemical properties.
Melting points and boiling points of Group 1 elements?
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.
What is special about the elements in the same group?
elements are in the same group since they react similarly to other elements in that group.
What Elements on the left side of the table are classified as what type of elements?
Group 1 Elements (elements in the first group [column]) are classed as Alkali Metals. Group 2 Elements (elements in the second group [column]) are classed as Alkaline Earth Metals. All elements not in a representative group are classed as Transition Metals. Group 3 Elements (elements in the third full group [coulumn]) are classed as Earth Metals
What elements have more predictable properties main group elements or transition elements?
main group elements
What are the elements in group 17?
Group 17 elements are called the halogens. Group 18 elements are called the noble gases.
What elements are in group 17?
Group 17 elements are called the halogens. Group 18 elements are called the noble gases.
