A section of the periodic table is shown below: A portion of two rows of the periodic table is shown. The first row reads two helium 4.003. The second row reads seven nitrogen 14.007, eight oxygen 15.999, nine flourine 18.998, and 10 neon 20.180. Helium and neon form the last column of the periodic table. Which of the following statements is true? Neon is more reactive than fluorine because neon needs only one electron to fill its outermost shell. Neon is more reactive than oxygen because neon has to lose only one electron to fill its outermost shell. Fluorine is more reactive than nitrogen because fluorine needs only one electron to fill its outermost shell. Fluorine is more reactive than neon because fluorine has to lose only one electron to fill its outermost shell.

The statement which is true is

Fluorine is more reactive than nitrogen because fluorine needs only one electron to fill its outermost shell.

Explanation

Fluorine has electron configuration of 1S²2S²2P⁵ while nitrogen has 1S²2S²2P³ electron configuration.

The 2P sub shell for nitrogen is half filled therefore it is sable than fluorine.

since p orbital can hold a maximum of 6 electrons, Fluorine requires 1 electron to completely fill it's 2P sub shell which make it more reactive than nitrogen.
