I NEED HELP!! PLEASE what is the predicted order of electronegativity values from least to greatest for elements in the second period?

A. li b>n>f
B. c b>n>f
D. there is no way to predict

C < N < O < F.
Electronegativity values decrease from top to bottom within a group of elements.
Hope this helps

Answercan utilize even low wind speed to produce electricity;

In reversible reaction chemistry equilibrium is attained when the forward and reverse reactions are taking place at the same rate, thus, the concentrations of reactants and products remain the same. a reversible reaction is a chemical reaction where the reactants form products that, in turn, react together to give the reactants back. in irreversible reactions on the other hand, the reactants react to form the products, which cannot revert back into reactants.
