JAMB - Chemistry (1987 - No. 20)
The greater the different in electronegativity between bonded atoms, the?
lower the polarity of the bond
higher the polarity of the bond
weaker the bond
higher the possibility of the substance formed being a molecule
توضیح
Bond polarity and ionic character increase with an increasing difference in electronegativity.
The electronegativity (χ) of an element is the relative ability of an atom to attract electrons to itself in a chemical compound and increases diagonally from the lower left of the periodic table to the upper right.
