fluorine, a nonmetal, has an electronegativity value of 4.0, and chlorine, a nonmetal, has a value of 3.0. the type of bond formed will be:

ionic
covalent
metallic
no way to determine the type of bond formed

➷ It would be a covalent bond most likely. It cannot be an ionic bond as the two elements have the same number of electrons. It also couldn't be a metallic bond as they are obviously not metals.

➶ Hope This Helps You!

➶ Good Luck (:

➶ Have A Great Day ^-^

The following is true for electronegativity and the bonds formed between atoms:

The difference in electromagnetically is 1.0 (4.0-3.0=1.0). Thus, the bond will be polar covalent, which is a type of covalent bond.

Let me know if you need any clarifications, thanks!

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
