Which element melting point is highest?
The metal with the highest melting point is tungsten, at 3,414 °C (6,177 °F; 3,687 K); this property makes tungsten excellent for use as electrical filaments in incandescent lamps.
What is trend of melting and boiling point in periodic table?
A trend can also been seen on descending a group. The melting and boiling points of the Group 1 elements decrease on descending the group. This is due to a decrease in the forces of attraction between the atoms. On crossing a period in the Periodic Table the atomic size decreases.
Which type of elements have low melting and boiling points?
Zn has no unpaired electron hence it has lowest melting and boiling point.
Which element has the highest boiling point?
The chemical element with the lowest boiling point is Helium and the element with the highest boiling point is Tungsten.
Which has the lowest melting point?
The chemical element with the lowest melting point is Helium and the element with the highest melting point is Carbon.
Which has the lowest boiling point?
Which element has the lowest melting and boiling point?
Which element has highest boiling point?
Why melting point and boiling point decreases down the group?
The decrease in melting and boiling points reflects the decrease in the strength of each metallic bond. The atoms in a metal are held together by the attraction of the nuclei to electrons which are delocalized over the whole metal mass.
Which elements have the highest boiling point?
Which element has highest and lowest boiling point?
What 5 elements have the lowest boiling point?

Which element has the lowest boiling point?
Helium
The chemical element with the lowest boiling point is Helium and the element with the highest boiling point is Tungsten.
What elements have a low boiling point?
The noble gases all have low boiling points : helium, at the top of group 0, has the lowest boiling point of any element.
Why does melting point increase across a period?
Melting and boiling points increase across the three metals because of the increasing strength of their metallic bonds. The number of electrons which each atom can contribute to the delocalized “sea of electrons” increases.
