Use the drop-down menus to identify the class of compounds to which each structure belongs. A skeletal chain goes up, down, up, down to C double bonded to O, up to O H. A skeletal chain goes up to O, down, up, down, up. A hexagonal ring is single bonded to C l on one corner. N has a pair of electron dots above, and is single bonded to R Superscript 1, wedge bonded to H, and wavy bonded to H.

explanation:

0.07 g/cm³

1.37 g/cm³

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.
