Consider the heating curve of water. As one moves along the line graph, through region III, the following statements apply. You may choose more than one answer.
A)
The water is beginning to boil
B)
The water temperature is increasing
09
The time elapsed is twenty-five minutes.
D
The kinetic energy of the molecules is increasing.
E)
The intermolecular attractions between water molecules are increasing.

the answer is c i took the test

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.
