The pictures below show samples of different substances,
The mass and volume of each sample differ from the mass and volume of the other samples. Is it possible for each sample
to contain 1 mol of each substance?
No, because they have different masses.
No, because they have different volumes.
Yes, because the number of moles is not dependent on the mass or the volume.
Yos hecause the number of moles is only dependent on the mass per unit volume.

explanation:

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.
