Electronegativity is the tendency of atom to attract shared pair of electron towards itself . Its value is out of 4 , and Fluorine is higly electronegative.
So,
D electronegativity, is the correct answer.
Most volcanoes and earthquakes occur along boundaries between tectonic plates because tectonic plates shift either spreading apart causing a earthquake or moving together which pushes the plate upwards causing a volcanoe
Explanation:
Formula for work done is as follows.
W =
where, k = proportionality constant = 


d = separation distance = 0.45 nm = 
Now, we will put the given values into the above formula and calculate work done as follows.
W =
=
= 
Thus, we can conclude that work required to increase the separation of the two ions to an infinite distance is
.
