The correct response would be C. Those in the outermost shell, and of highest electron energy are the valence electrons for potassium.
I believe it is electronegativity..... because electronegativity is the ability of an atom to attract electron to itself
Answer:
The chemical elements most likely to form covalent bonds are those that share electrons, such as carbon, as opposed to those that take them from another element to form an ionic bond. In general, they are nonmetals with similar electronegativities.
Explanation:
An acid is an ionic compound that produces positive hydrogen ions when dissolved in water. Acids taste sour and turn blue litmus paper red. A base is an ionic compound that produces negative hydroxide ions when dissolved in water. Bases taste bitter and turn red litmus paper blue.
