fluorine Which of the following is the least electronegative element? potossium nitrogen oxygen

## Step 1<br />Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. The Pauling scale is used to measure electronegativity, with higher values indicating greater electronegativity.<br /><br />## Step 2<br />The given options are potassium (K), nitrogen (N), and oxygen (O). According to the Pauling scale, the electronegativities of these elements are as follows:<br />- Potassium (K): 0.82<br />- Nitrogen (N): 3.04<br />- Oxygen (O): 3.44<br /><br />## Step 3<br />Comparing these values, it is clear that potassium has the lowest electronegativity. Therefore, the correct answer is potassium.
