I WILL GIVE BRAINLIEST IF IT IS CORRECT Match the term and definition Lesson 2.13 Question 6 options: wave height wavelength crest trough 1. top of a wave 2. lowest point of the wave 3. distance between crest and trough 4. Distance from crest to crest or the distance from trough to trough

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.
