Hamid made this table to organize his notes on the properties of acids and bases. A 2-column table with 2 rows. The first column labeled acids has entries taste sour, react with carbohydrates. The second column labeled baseshas entries conduct electric current, form hydrogen gas with metals. Which property is in the wrong column? taste sour react with carbonates conduct electric current form hydrogen gas with metals.

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.
