Arrange the following in order of decreasing stability. a blank molecular orbital diagram (part a 1 figure) has been provided to you.
rank the fluorine species from most to least stable. to rank items as equivalent, overlap them. f2, f2+, f2-

Then F- has greater stability, then F follows and the least stable is F +

Explanation:

Fluorine is an element of group 17 (VII A) that has 7 electrons in its last layer. This element tends to form anions (earning an electron). If the fluorine gains an electron, it acquires the electronic configuration of the neon (noble gas), forming the anion F-. This makes the flour acquire greater stability. and consider the F- as the most stable anion.

The F + ion is the most unstable element because in order to form it is called the Ionization Energy, which is the energy needed to start an electron to a gaseous atom, isolated and in a fundamental state. The electrons are attracted to the nucleus and it is necessary to provide energy to start them. In addition, the F +, having a positive charge, will have a greater tendency to acquire 2 electrons to complete its last layer and achieve stability, while the F has a tendency to acquire only 1 electron and form the F- anion to acquire stability.

Then F- has greater stability, then F follows and the least stable is F + .
