Gabriel and his friend found a piece of metal which they want to identify. Here is what they figure out so far:
Mass of this metal is 50 g
Volume of this metal is 5.2 cm

Zinc is the metal that your looking for there bud

Explanation:

"the periodic table is arranged in order of atomic number."

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.
