The graph shows the melting points of the first thirty-six elements in the periodic table. image

Which statement is supported by the information in the graph?

A.
Nonmetal elements generally have lower melting points.

B.
The melting point increases as the atomic number increases.

C.
The melting point decreases as the atomic number increases.

D.
Metal elements generally melt slower than nonmetal elements.

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
