Place the following in order of increasing electronegativity. N As K Ca

Question

Quizplus · Accepted Answer

Electronegativity increases across a period from left to right and decreases down a group in the periodic table. Therefore, among the given elements, potassium (K) and calcium (Ca) are metals with lower electronegativities compared to arsenic (As) and nitrogen (N), which are nonmetals. K and Ca are in the same period with K being to the left of Ca, so K is less electronegative than Ca. As and N are also in the same group, but As is below N, making N more electronegative than As. Thus, the correct order is K < Ca < As < N.
