Many different arrangements of electrons in an atom (configurations) are possible. Orbital diagrams are used to describe the possible locations of electrons and the resulting configurations produced by many electrons in a single atom. Drawing an orbital diagram shows the relative energy level of many different orbitals. Statements below refer to the order of boxes from left to right. Indicate which of the following statements about energy levels in a multi-electron system are true or false.

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.
