The difference in the electronegativity of two atoms determines their bond type. If the electronegativity difference is more than 1.7, the bond will have an ionic character. If the electronegativity difference is between 0.4 and 1.7, the bond will have a polar covalent character. Lastly, if the electronegativity difference is less than 0.4, the bond will have a nonpolar covalent character.
If the difference in electronegativity between elements P and Q is 3.0, which is considered a large difference, the bond that will be formed between them is indeed an ionic bond.
In an ionic bond, there is a complete transfer of electrons from one atom to another. This transfer occurs when there is a significant difference in electronegativity between the two elements involved, typically greater than 1.7. The atom with higher electronegativity gains electrons to become a negatively charged ion (anion), while the atom with lower electronegativity loses electrons to become a positively charged ion (cation).
Therefore, the correct answer is D. ionic.
Note that when the EN value difference is too large, ie greater than 1.7 then the bond formed is ionic/electrovalent. But when the EN value difference is greater and equal to 0.5, then the bond formed is polar covalent bond. And when the EN value difference is less than 0.5, then the bond formed is the non-polar covalent bond.
When the electronegativity difference(Δx) is
large than 0.7 i.e Δx ≥ 0.7 the bond forme
is electrovalent (Ionic bond). But when the
electronegativity difference smaller than 0.5
i.e Δx≤ 0.5 the bond formed is covalent
N.B; Zero electronegativity difference is eqial to non polar covalent
D is d correct answer. becaues one of d two (P and Q) Will lose dat 3 electron for other to gain that 3 electron to complete its outshall and d process is called ironic bond.
The answer is D it means the difference is highly electro negative and the other will be highly electro positive
