If the difference in electronegativity of elements P and Q is 3.0. The bond that will be formed between them is

The difference in electronegativity between two elements determines the type of bond they will form. Electronegativity is the measure of an atom's ability to attract electrons towards itself in a covalent bond. If the difference in electronegativity between two elements is greater than 1.7, the bond between them is considered to be ionic. In an ionic bond, one atom will completely transfer its valence electrons to the other, resulting in the formation of ions with opposite charges that are held together by electrostatic forces. However, if the difference in electronegativity is less than 1.7, the bond between the elements is considered to be covalent. In a covalent bond, the atoms share valence electrons to fill their outermost energy levels. In the given question, the difference in electronegativity of elements P and Q is 3.0, which is greater than 1.7. Hence, the bond between them will be an ionic bond. Therefore, the answer is.
