Linnaeus proved that many organisms, which were classified as plants by Aristotle, were animals. Aristotle and Linnaeus worked side by side examining organisms on man

its first and third is your answer i did the qustion the fourth isnt right

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.
