We’re being asked to rank the given elements by increasing electronegativity.
Recall that the most electronegative element is fluorine (F) while the least electronegative element is francium (Fr).
This means the trend for electronegativity is as follows: it increases from left to right and decreases down a period in the periodic table.
The given elements are:
List the elements Ca, Si, and K in order of increasing electronegativity.
a) Ca < K < Si
b) K < Si < Ca
c) Si < Ca < K
d) K < Ca < Si
